Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021874, here are decompositions:

  • 13 + 1021861 = 1021874
  • 37 + 1021837 = 1021874
  • 43 + 1021831 = 1021874
  • 67 + 1021807 = 1021874
  • 97 + 1021777 = 1021874
  • 127 + 1021747 = 1021874
  • 163 + 1021711 = 1021874
  • 211 + 1021663 = 1021874

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 1874 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1874-02-01 (DMMYYYY (Euro, single-digit day))
  • 1874-10-02 (MMDYYYY (US, single-digit day))
  • 1874-02-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,021,874 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1021874 first appears in π at position 888,211 of the decimal expansion (the 888,211ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
