Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002890, here are decompositions:

  • 3 + 1002887 = 1002890
  • 19 + 1002871 = 1002890
  • 37 + 1002853 = 1002890
  • 73 + 1002817 = 1002890
  • 103 + 1002787 = 1002890
  • 139 + 1002751 = 1002890
  • 151 + 1002739 = 1002890
  • 181 + 1002709 = 1002890

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 1,002,890 and was likely granted around 1911.

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