Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000978, here are decompositions:

  • 5 + 1000973 = 1000978
  • 47 + 1000931 = 1000978
  • 59 + 1000919 = 1000978
  • 71 + 1000907 = 1000978
  • 89 + 1000889 = 1000978
  • 131 + 1000847 = 1000978
  • 149 + 1000829 = 1000978
  • 257 + 1000721 = 1000978

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 1,000,978 and was likely granted around 1911.

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