Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142758, here are decompositions:

  • 47 + 142711 = 142758
  • 59 + 142699 = 142758
  • 61 + 142697 = 142758
  • 101 + 142657 = 142758
  • 139 + 142619 = 142758
  • 149 + 142609 = 142758
  • 151 + 142607 = 142758
  • 157 + 142601 = 142758

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 142,758 and was likely granted around 1872.

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