Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125162, here are decompositions:

  • 13 + 125149 = 125162
  • 31 + 125131 = 125162
  • 43 + 125119 = 125162
  • 61 + 125101 = 125162
  • 109 + 125053 = 125162
  • 181 + 124981 = 125162
  • 211 + 124951 = 125162
  • 379 + 124783 = 125162

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 125,162 and was likely granted around 1871.

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