Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707858, here are decompositions:

  • 17 + 8707841 = 8707858
  • 41 + 8707817 = 8707858
  • 197 + 8707661 = 8707858
  • 227 + 8707631 = 8707858
  • 251 + 8707607 = 8707858
  • 479 + 8707379 = 8707858
  • 569 + 8707289 = 8707858
  • 617 + 8707241 = 8707858

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 8,707,858 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 8707858 first appears in π at position 943,356 of the decimal expansion (the 943,356ordinal-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.
