Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519172, here are decompositions:

  • 11 + 519161 = 519172
  • 41 + 519131 = 519172
  • 53 + 519119 = 519172
  • 83 + 519089 = 519172
  • 89 + 519083 = 519172
  • 191 + 518981 = 519172
  • 239 + 518933 = 519172
  • 359 + 518813 = 519172

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 519,172 and was likely granted around 1894.

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