Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990850, here are decompositions:

  • 41 + 990809 = 990850
  • 53 + 990797 = 990850
  • 83 + 990767 = 990850
  • 89 + 990761 = 990850
  • 131 + 990719 = 990850
  • 251 + 990599 = 990850
  • 257 + 990593 = 990850
  • 347 + 990503 = 990850

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 990,850 and was likely granted around 1911.

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