Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019864, here are decompositions:

  • 3 + 1019861 = 1019864
  • 7 + 1019857 = 1019864
  • 37 + 1019827 = 1019864
  • 151 + 1019713 = 1019864
  • 163 + 1019701 = 1019864
  • 331 + 1019533 = 1019864
  • 397 + 1019467 = 1019864
  • 421 + 1019443 = 1019864

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 9864 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 9864-10-01 (MMDYYYY (US, single-digit day))
  • 9864-01-10 (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 1,019,864 and was likely granted around 1911.

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

Position in π

The digit sequence 1019864 first appears in π at position 20,430 of the decimal expansion (the 20,430ordinal-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.
