Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142502, here are decompositions:

  • 271 + 142231 = 142502
  • 313 + 142189 = 142502
  • 379 + 142123 = 142502
  • 463 + 142039 = 142502
  • 541 + 141961 = 142502
  • 571 + 141931 = 142502
  • 631 + 141871 = 142502
  • 673 + 141829 = 142502

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 142,502 and was likely granted around 1872.

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