Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519998, here are decompositions:

  • 67 + 519931 = 519998
  • 79 + 519919 = 519998
  • 109 + 519889 = 519998
  • 181 + 519817 = 519998
  • 211 + 519787 = 519998
  • 229 + 519769 = 519998
  • 307 + 519691 = 519998
  • 331 + 519667 = 519998

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 519,998 and was likely granted around 1894.

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