Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757870, here are decompositions:

  • 13 + 8757857 = 8757870
  • 19 + 8757851 = 8757870
  • 41 + 8757829 = 8757870
  • 53 + 8757817 = 8757870
  • 61 + 8757809 = 8757870
  • 71 + 8757799 = 8757870
  • 101 + 8757769 = 8757870
  • 113 + 8757757 = 8757870

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 8,757,870 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 8757870 first appears in π at position 746,165 of the decimal expansion (the 746,165ordinal-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.
