Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145804, here are decompositions:

  • 5 + 145799 = 145804
  • 47 + 145757 = 145804
  • 83 + 145721 = 145804
  • 101 + 145703 = 145804
  • 167 + 145637 = 145804
  • 227 + 145577 = 145804
  • 257 + 145547 = 145804
  • 293 + 145511 = 145804

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 145,804 and was likely granted around 1873.

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