Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004778, here are decompositions:

  • 17 + 1004761 = 1004778
  • 29 + 1004749 = 1004778
  • 31 + 1004747 = 1004778
  • 41 + 1004737 = 1004778
  • 101 + 1004677 = 1004778
  • 107 + 1004671 = 1004778
  • 109 + 1004669 = 1004778
  • 127 + 1004651 = 1004778

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 1,004,778 and was likely granted around 1911.

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