Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122586, here are decompositions:

  • 7 + 122579 = 122586
  • 29 + 122557 = 122586
  • 53 + 122533 = 122586
  • 59 + 122527 = 122586
  • 83 + 122503 = 122586
  • 89 + 122497 = 122586
  • 97 + 122489 = 122586
  • 109 + 122477 = 122586

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 122,586 and was likely granted around 1871.

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

Position in π

The digit sequence 122586 first appears in π at position 814,959 of the decimal expansion (the 814,959ordinal-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.
