Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005012, here are decompositions:

  • 5 + 1005007 = 1005012
  • 31 + 1004981 = 1005012
  • 101 + 1004911 = 1005012
  • 109 + 1004903 = 1005012
  • 139 + 1004873 = 1005012
  • 233 + 1004779 = 1005012
  • 251 + 1004761 = 1005012
  • 263 + 1004749 = 1005012

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 1,005,012 and was likely granted around 1911.

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