Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122270, here are decompositions:

  • 3 + 122267 = 122270
  • 7 + 122263 = 122270
  • 19 + 122251 = 122270
  • 61 + 122209 = 122270
  • 67 + 122203 = 122270
  • 97 + 122173 = 122270
  • 103 + 122167 = 122270
  • 139 + 122131 = 122270

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 122,270 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 122270 first appears in π at position 135,042 of the decimal expansion (the 135,042ordinal-suffix:nd 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.
