Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003818, here are decompositions:

  • 31 + 1003787 = 1003818
  • 47 + 1003771 = 1003818
  • 61 + 1003757 = 1003818
  • 71 + 1003747 = 1003818
  • 89 + 1003729 = 1003818
  • 107 + 1003711 = 1003818
  • 139 + 1003679 = 1003818
  • 191 + 1003627 = 1003818

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 1,003,818 and was likely granted around 1911.

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