Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005530, here are decompositions:

  • 3 + 1005527 = 1005530
  • 37 + 1005493 = 1005530
  • 73 + 1005457 = 1005530
  • 103 + 1005427 = 1005530
  • 139 + 1005391 = 1005530
  • 157 + 1005373 = 1005530
  • 181 + 1005349 = 1005530
  • 199 + 1005331 = 1005530

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 1,005,530 and was likely granted around 1911.

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