Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122402, here are decompositions:

  • 3 + 122399 = 122402
  • 13 + 122389 = 122402
  • 79 + 122323 = 122402
  • 103 + 122299 = 122402
  • 139 + 122263 = 122402
  • 151 + 122251 = 122402
  • 193 + 122209 = 122402
  • 199 + 122203 = 122402

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 122,402 and was likely granted around 1871.

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