Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988740, here are decompositions:

  • 7 + 988733 = 988740
  • 13 + 988727 = 988740
  • 29 + 988711 = 988740
  • 47 + 988693 = 988740
  • 59 + 988681 = 988740
  • 79 + 988661 = 988740
  • 89 + 988651 = 988740
  • 97 + 988643 = 988740

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 988,740 and was likely granted around 1911.

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