Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691858, here are decompositions:

  • 5 + 8691853 = 8691858
  • 31 + 8691827 = 8691858
  • 59 + 8691799 = 8691858
  • 107 + 8691751 = 8691858
  • 127 + 8691731 = 8691858
  • 191 + 8691667 = 8691858
  • 269 + 8691589 = 8691858
  • 271 + 8691587 = 8691858

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 8,691,858 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 8691858 first appears in π at position 892,082 of the decimal expansion (the 892,082ordinal-suffix:nd 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.
