Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109778, here are decompositions:

  • 37 + 109741 = 109778
  • 61 + 109717 = 109778
  • 139 + 109639 = 109778
  • 157 + 109621 = 109778
  • 181 + 109597 = 109778
  • 199 + 109579 = 109778
  • 211 + 109567 = 109778
  • 241 + 109537 = 109778

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 109,778 and was likely granted around 1871.

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