Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142960, here are decompositions:

  • 11 + 142949 = 142960
  • 53 + 142907 = 142960
  • 89 + 142871 = 142960
  • 149 + 142811 = 142960
  • 173 + 142787 = 142960
  • 227 + 142733 = 142960
  • 263 + 142697 = 142960
  • 353 + 142607 = 142960

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 142,960 and was likely granted around 1872.

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