Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600870, here are decompositions:

  • 127 + 8600743 = 8600870
  • 151 + 8600719 = 8600870
  • 193 + 8600677 = 8600870
  • 241 + 8600629 = 8600870
  • 277 + 8600593 = 8600870
  • 283 + 8600587 = 8600870
  • 337 + 8600533 = 8600870
  • 373 + 8600497 = 8600870

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 8,600,870 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 8600870 first appears in π at position 683,995 of the decimal expansion (the 683,995ordinal-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.
