Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998860, here are decompositions:

  • 3 + 998857 = 998860
  • 17 + 998843 = 998860
  • 29 + 998831 = 998860
  • 41 + 998819 = 998860
  • 47 + 998813 = 998860
  • 101 + 998759 = 998860
  • 173 + 998687 = 998860
  • 179 + 998681 = 998860

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 998,860 and was likely granted around 1911.

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