Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005078, here are decompositions:

  • 5 + 1005073 = 1005078
  • 7 + 1005071 = 1005078
  • 29 + 1005049 = 1005078
  • 37 + 1005041 = 1005078
  • 59 + 1005019 = 1005078
  • 71 + 1005007 = 1005078
  • 97 + 1004981 = 1005078
  • 101 + 1004977 = 1005078

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 1,005,078 and was likely granted around 1911.

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