Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591812, here are decompositions:

  • 3 + 8591809 = 8591812
  • 41 + 8591771 = 8591812
  • 101 + 8591711 = 8591812
  • 149 + 8591663 = 8591812
  • 179 + 8591633 = 8591812
  • 239 + 8591573 = 8591812
  • 263 + 8591549 = 8591812
  • 269 + 8591543 = 8591812

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 8,591,812 and was likely granted around 2013.

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

Position in π

The digit sequence 8591812 first appears in π at position 931,429 of the decimal expansion (the 931,429ordinal-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.
