Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502218, here are decompositions:

  • 37 + 502181 = 502218
  • 47 + 502171 = 502218
  • 97 + 502121 = 502218
  • 131 + 502087 = 502218
  • 137 + 502081 = 502218
  • 139 + 502079 = 502218
  • 179 + 502039 = 502218
  • 251 + 501967 = 502218

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 502,218 and was likely granted around 1893.

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