Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981602, here are decompositions:

  • 3 + 981599 = 981602
  • 79 + 981523 = 981602
  • 109 + 981493 = 981602
  • 151 + 981451 = 981602
  • 163 + 981439 = 981602
  • 211 + 981391 = 981602
  • 229 + 981373 = 981602
  • 283 + 981319 = 981602

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 981,602 and was likely granted around 1910.

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