Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151560, here are decompositions:

  • 7 + 151553 = 151560
  • 11 + 151549 = 151560
  • 23 + 151537 = 151560
  • 29 + 151531 = 151560
  • 37 + 151523 = 151560
  • 43 + 151517 = 151560
  • 53 + 151507 = 151560
  • 61 + 151499 = 151560

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 151,560 and was likely granted around 1873.

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