Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998750, here are decompositions:

  • 7 + 998743 = 998750
  • 13 + 998737 = 998750
  • 61 + 998689 = 998750
  • 97 + 998653 = 998750
  • 127 + 998623 = 998750
  • 199 + 998551 = 998750
  • 211 + 998539 = 998750
  • 223 + 998527 = 998750

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 998,750 and was likely granted around 1911.

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