Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500990, here are decompositions:

  • 13 + 500977 = 500990
  • 37 + 500953 = 500990
  • 43 + 500947 = 500990
  • 67 + 500923 = 500990
  • 79 + 500911 = 500990
  • 103 + 500887 = 500990
  • 109 + 500881 = 500990
  • 151 + 500839 = 500990

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 500,990 and was likely granted around 1893.

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