Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008870, here are decompositions:

  • 7 + 1008863 = 1008870
  • 11 + 1008859 = 1008870
  • 13 + 1008857 = 1008870
  • 17 + 1008853 = 1008870
  • 19 + 1008851 = 1008870
  • 41 + 1008829 = 1008870
  • 53 + 1008817 = 1008870
  • 61 + 1008809 = 1008870

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 1,008,870 and was likely granted around 1911.

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