Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490392, here are decompositions:

  • 53 + 490339 = 490392
  • 79 + 490313 = 490392
  • 83 + 490309 = 490392
  • 109 + 490283 = 490392
  • 151 + 490241 = 490392
  • 191 + 490201 = 490392
  • 223 + 490169 = 490392
  • 233 + 490159 = 490392

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 490,392 and was likely granted around 1892.

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