Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188570, here are decompositions:

  • 7 + 188563 = 188570
  • 37 + 188533 = 188570
  • 43 + 188527 = 188570
  • 79 + 188491 = 188570
  • 97 + 188473 = 188570
  • 127 + 188443 = 188570
  • 139 + 188431 = 188570
  • 163 + 188407 = 188570

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 188,570 and was likely granted around 1875.

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