Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761810, here are decompositions:

  • 3 + 8761807 = 8761810
  • 47 + 8761763 = 8761810
  • 59 + 8761751 = 8761810
  • 89 + 8761721 = 8761810
  • 107 + 8761703 = 8761810
  • 179 + 8761631 = 8761810
  • 191 + 8761619 = 8761810
  • 263 + 8761547 = 8761810

Showing the first eight; more decompositions exist.

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 8,761,810 and was likely granted around 2014.

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

Position in π

The digit sequence 8761810 first appears in π at position 113,849 of the decimal expansion (the 113,849ordinal-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.
