Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478874, here are decompositions:

  • 3 + 478871 = 478874
  • 13 + 478861 = 478874
  • 31 + 478843 = 478874
  • 43 + 478831 = 478874
  • 61 + 478813 = 478874
  • 73 + 478801 = 478874
  • 127 + 478747 = 478874
  • 163 + 478711 = 478874

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 478,874 and was likely granted around 1892.

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