Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682780, here are decompositions:

  • 17 + 8682763 = 8682780
  • 23 + 8682757 = 8682780
  • 31 + 8682749 = 8682780
  • 37 + 8682743 = 8682780
  • 53 + 8682727 = 8682780
  • 59 + 8682721 = 8682780
  • 61 + 8682719 = 8682780
  • 79 + 8682701 = 8682780

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 8,682,780 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 8682780 first appears in π at position 350,623 of the decimal expansion (the 350,623ordinal-suffix:rd 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.
