Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122256, here are decompositions:

  • 5 + 122251 = 122256
  • 37 + 122219 = 122256
  • 47 + 122209 = 122256
  • 53 + 122203 = 122256
  • 83 + 122173 = 122256
  • 89 + 122167 = 122256
  • 107 + 122149 = 122256
  • 109 + 122147 = 122256

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 122,256 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 122256 first appears in π at position 659,246 of the decimal expansion (the 659,246ordinal-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.
