Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990804, here are decompositions:

  • 5 + 990799 = 990804
  • 7 + 990797 = 990804
  • 37 + 990767 = 990804
  • 43 + 990761 = 990804
  • 71 + 990733 = 990804
  • 97 + 990707 = 990804
  • 131 + 990673 = 990804
  • 167 + 990637 = 990804

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 990,804 and was likely granted around 1911.

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