Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490340, here are decompositions:

  • 31 + 490309 = 490340
  • 73 + 490267 = 490340
  • 139 + 490201 = 490340
  • 157 + 490183 = 490340
  • 181 + 490159 = 490340
  • 223 + 490117 = 490340
  • 229 + 490111 = 490340
  • 283 + 490057 = 490340

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 490,340 and was likely granted around 1892.

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