Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142224, here are decompositions:

  • 7 + 142217 = 142224
  • 13 + 142211 = 142224
  • 31 + 142193 = 142224
  • 41 + 142183 = 142224
  • 67 + 142157 = 142224
  • 73 + 142151 = 142224
  • 101 + 142123 = 142224
  • 113 + 142111 = 142224

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 142,224 and was likely granted around 1872.

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