Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125288, here are decompositions:

  • 19 + 125269 = 125288
  • 67 + 125221 = 125288
  • 139 + 125149 = 125288
  • 157 + 125131 = 125288
  • 181 + 125107 = 125288
  • 271 + 125017 = 125288
  • 307 + 124981 = 125288
  • 337 + 124951 = 125288

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 125,288 and was likely granted around 1871.

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