Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518162, here are decompositions:

  • 3 + 518159 = 518162
  • 31 + 518131 = 518162
  • 61 + 518101 = 518162
  • 79 + 518083 = 518162
  • 103 + 518059 = 518162
  • 163 + 517999 = 518162
  • 181 + 517981 = 518162
  • 331 + 517831 = 518162

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 518,162 and was likely granted around 1894.

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