Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142712, here are decompositions:

  • 13 + 142699 = 142712
  • 103 + 142609 = 142712
  • 139 + 142573 = 142712
  • 211 + 142501 = 142712
  • 331 + 142381 = 142712
  • 523 + 142189 = 142712
  • 601 + 142111 = 142712
  • 613 + 142099 = 142712

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 142,712 and was likely granted around 1872.

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