Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157550, here are decompositions:

  • 7 + 157543 = 157550
  • 31 + 157519 = 157550
  • 37 + 157513 = 157550
  • 61 + 157489 = 157550
  • 67 + 157483 = 157550
  • 73 + 157477 = 157550
  • 139 + 157411 = 157550
  • 157 + 157393 = 157550

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 157,550 and was likely granted around 1873.

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