Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027790, here are decompositions:

  • 3 + 1027787 = 1027790
  • 7 + 1027783 = 1027790
  • 13 + 1027777 = 1027790
  • 31 + 1027759 = 1027790
  • 37 + 1027753 = 1027790
  • 73 + 1027717 = 1027790
  • 97 + 1027693 = 1027790
  • 103 + 1027687 = 1027790

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 7790 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7790-02-01 (DMMYYYY (Euro, single-digit day))
  • 7790-10-02 (MMDYYYY (US, single-digit day))
  • 7790-02-10 (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 1,027,790 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 1027790 first appears in π at position 478,659 of the decimal expansion (the 478,659ordinal-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.
