Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002198, here are decompositions:

  • 7 + 1002191 = 1002198
  • 47 + 1002151 = 1002198
  • 89 + 1002109 = 1002198
  • 97 + 1002101 = 1002198
  • 107 + 1002091 = 1002198
  • 137 + 1002061 = 1002198
  • 149 + 1002049 = 1002198
  • 181 + 1002017 = 1002198

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 1,002,198 and was likely granted around 1911.

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