Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991056, here are decompositions:

  • 13 + 991043 = 991056
  • 19 + 991037 = 991056
  • 29 + 991027 = 991056
  • 47 + 991009 = 991056
  • 67 + 990989 = 991056
  • 83 + 990973 = 991056
  • 89 + 990967 = 991056
  • 103 + 990953 = 991056

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 991,056 and was likely granted around 1911.

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