Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122140, here are decompositions:

  • 23 + 122117 = 122140
  • 41 + 122099 = 122140
  • 59 + 122081 = 122140
  • 71 + 122069 = 122140
  • 89 + 122051 = 122140
  • 101 + 122039 = 122140
  • 107 + 122033 = 122140
  • 113 + 122027 = 122140

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 122,140 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 122140 first appears in π at position 576,309 of the decimal expansion (the 576,309ordinal-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.
