Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999450, here are decompositions:

  • 13 + 999437 = 999450
  • 17 + 999433 = 999450
  • 19 + 999431 = 999450
  • 61 + 999389 = 999450
  • 73 + 999377 = 999450
  • 79 + 999371 = 999450
  • 163 + 999287 = 999450
  • 181 + 999269 = 999450

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 999,450 and was likely granted around 1911.

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