Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735780, here are decompositions:

  • 3 + 8735777 = 8735780
  • 19 + 8735761 = 8735780
  • 37 + 8735743 = 8735780
  • 103 + 8735677 = 8735780
  • 199 + 8735581 = 8735780
  • 223 + 8735557 = 8735780
  • 271 + 8735509 = 8735780
  • 331 + 8735449 = 8735780

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 8,735,780 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 8735780 first appears in π at position 601,329 of the decimal expansion (the 601,329ordinal-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.
