Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121078, here are decompositions:

  • 11 + 121067 = 121078
  • 17 + 121061 = 121078
  • 59 + 121019 = 121078
  • 71 + 121007 = 121078
  • 101 + 120977 = 121078
  • 131 + 120947 = 121078
  • 137 + 120941 = 121078
  • 149 + 120929 = 121078

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 121,078 and was likely granted around 1871.

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