Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977920, here are decompositions:

  • 23 + 977897 = 977920
  • 59 + 977861 = 977920
  • 71 + 977849 = 977920
  • 89 + 977831 = 977920
  • 101 + 977819 = 977920
  • 107 + 977813 = 977920
  • 173 + 977747 = 977920
  • 197 + 977723 = 977920

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 977,920 and was likely granted around 1910.

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