Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654658, here are decompositions:

  • 17 + 8654641 = 8654658
  • 37 + 8654621 = 8654658
  • 41 + 8654617 = 8654658
  • 79 + 8654579 = 8654658
  • 137 + 8654521 = 8654658
  • 191 + 8654467 = 8654658
  • 197 + 8654461 = 8654658
  • 211 + 8654447 = 8654658

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 8,654,658 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 8654658 first appears in π at position 145,588 of the decimal expansion (the 145,588ordinal-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.
