Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151550, here are decompositions:

  • 13 + 151537 = 151550
  • 19 + 151531 = 151550
  • 43 + 151507 = 151550
  • 67 + 151483 = 151550
  • 73 + 151477 = 151550
  • 79 + 151471 = 151550
  • 127 + 151423 = 151550
  • 193 + 151357 = 151550

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 151,550 and was likely granted around 1873.

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