Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003870, here are decompositions:

  • 29 + 1003841 = 1003870
  • 53 + 1003817 = 1003870
  • 83 + 1003787 = 1003870
  • 107 + 1003763 = 1003870
  • 113 + 1003757 = 1003870
  • 137 + 1003733 = 1003870
  • 191 + 1003679 = 1003870
  • 239 + 1003631 = 1003870

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 1,003,870 and was likely granted around 1911.

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