Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123122, here are decompositions:

  • 31 + 123091 = 123122
  • 73 + 123049 = 123122
  • 151 + 122971 = 123122
  • 193 + 122929 = 123122
  • 283 + 122839 = 123122
  • 379 + 122743 = 123122
  • 421 + 122701 = 123122
  • 523 + 122599 = 123122

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 123,122 and was likely granted around 1871.

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