Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991102, here are decompositions:

  • 11 + 991091 = 991102
  • 23 + 991079 = 991102
  • 29 + 991073 = 991102
  • 59 + 991043 = 991102
  • 71 + 991031 = 991102
  • 113 + 990989 = 991102
  • 149 + 990953 = 991102
  • 179 + 990923 = 991102

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 991,102 and was likely granted around 1911.

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