Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478090, here are decompositions:

  • 3 + 478087 = 478090
  • 23 + 478067 = 478090
  • 89 + 478001 = 478090
  • 113 + 477977 = 478090
  • 149 + 477941 = 478090
  • 191 + 477899 = 478090
  • 227 + 477863 = 478090
  • 233 + 477857 = 478090

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 478,090 and was likely granted around 1892.

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