Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125402, here are decompositions:

  • 3 + 125399 = 125402
  • 19 + 125383 = 125402
  • 31 + 125371 = 125402
  • 73 + 125329 = 125402
  • 103 + 125299 = 125402
  • 181 + 125221 = 125402
  • 271 + 125131 = 125402
  • 283 + 125119 = 125402

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 125,402 and was likely granted around 1871.

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