Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185150, here are decompositions:

  • 13 + 185137 = 185150
  • 19 + 185131 = 185150
  • 61 + 185089 = 185150
  • 73 + 185077 = 185150
  • 79 + 185071 = 185150
  • 151 + 184999 = 185150
  • 157 + 184993 = 185150
  • 181 + 184969 = 185150

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 185,150 and was likely granted around 1875.

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