Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000390, here are decompositions:

  • 23 + 1000367 = 1000390
  • 101 + 1000289 = 1000390
  • 137 + 1000253 = 1000390
  • 179 + 1000211 = 1000390
  • 191 + 1000199 = 1000390
  • 197 + 1000193 = 1000390
  • 239 + 1000151 = 1000390
  • 257 + 1000133 = 1000390

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 1,000,390 and was likely granted around 1911.

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