Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005100, here are decompositions:

  • 29 + 1005071 = 1005100
  • 59 + 1005041 = 1005100
  • 71 + 1005029 = 1005100
  • 113 + 1004987 = 1005100
  • 137 + 1004963 = 1005100
  • 197 + 1004903 = 1005100
  • 227 + 1004873 = 1005100
  • 353 + 1004747 = 1005100

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 1,005,100 and was likely granted around 1911.

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