Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499240, here are decompositions:

  • 11 + 499229 = 499240
  • 29 + 499211 = 499240
  • 59 + 499181 = 499240
  • 83 + 499157 = 499240
  • 89 + 499151 = 499240
  • 101 + 499139 = 499240
  • 107 + 499133 = 499240
  • 113 + 499127 = 499240

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 499,240 and was likely granted around 1893.

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