Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123170, here are decompositions:

  • 43 + 123127 = 123170
  • 79 + 123091 = 123170
  • 139 + 123031 = 123170
  • 163 + 123007 = 123170
  • 199 + 122971 = 123170
  • 241 + 122929 = 123170
  • 283 + 122887 = 123170
  • 331 + 122839 = 123170

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 123,170 and was likely granted around 1871.

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