Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003978, here are decompositions:

  • 47 + 1003931 = 1003978
  • 71 + 1003907 = 1003978
  • 89 + 1003889 = 1003978
  • 137 + 1003841 = 1003978
  • 191 + 1003787 = 1003978
  • 347 + 1003631 = 1003978
  • 359 + 1003619 = 1003978
  • 389 + 1003589 = 1003978

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 1,003,978 and was likely granted around 1911.

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