Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002002, here are decompositions:

  • 13 + 1001989 = 1002002
  • 19 + 1001983 = 1002002
  • 61 + 1001941 = 1002002
  • 163 + 1001839 = 1002002
  • 181 + 1001821 = 1002002
  • 193 + 1001809 = 1002002
  • 373 + 1001629 = 1002002
  • 409 + 1001593 = 1002002

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

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