Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157518, here are decompositions:

  • 5 + 157513 = 157518
  • 29 + 157489 = 157518
  • 41 + 157477 = 157518
  • 61 + 157457 = 157518
  • 89 + 157429 = 157518
  • 107 + 157411 = 157518
  • 167 + 157351 = 157518
  • 191 + 157327 = 157518

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 157,518 and was likely granted around 1873.

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