Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006220, here are decompositions:

  • 3 + 1006217 = 1006220
  • 31 + 1006189 = 1006220
  • 43 + 1006177 = 1006220
  • 67 + 1006153 = 1006220
  • 73 + 1006147 = 1006220
  • 97 + 1006123 = 1006220
  • 157 + 1006063 = 1006220
  • 199 + 1006021 = 1006220

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 1,006,220 and was likely granted around 1911.

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