Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003520, here are decompositions:

  • 3 + 1003517 = 1003520
  • 13 + 1003507 = 1003520
  • 103 + 1003417 = 1003520
  • 109 + 1003411 = 1003520
  • 139 + 1003381 = 1003520
  • 151 + 1003369 = 1003520
  • 157 + 1003363 = 1003520
  • 229 + 1003291 = 1003520

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 1,003,520 and was likely granted around 1911.

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