Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997620, here are decompositions:

  • 11 + 997609 = 997620
  • 23 + 997597 = 997620
  • 31 + 997589 = 997620
  • 37 + 997583 = 997620
  • 47 + 997573 = 997620
  • 67 + 997553 = 997620
  • 73 + 997547 = 997620
  • 79 + 997541 = 997620

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 997,620 and was likely granted around 1911.

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