Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047978, here are decompositions:

  • 7 + 1047971 = 1047978
  • 17 + 1047961 = 1047978
  • 37 + 1047941 = 1047978
  • 97 + 1047881 = 1047978
  • 137 + 1047841 = 1047978
  • 157 + 1047821 = 1047978
  • 199 + 1047779 = 1047978
  • 227 + 1047751 = 1047978

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 7978 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7978-04-01 (DMMYYYY (Euro, single-digit day))
  • 7978-10-04 (MMDYYYY (US, single-digit day))
  • 7978-04-10 (DDMYYYY (Euro, single-digit month))
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 1,047,978 and was likely granted around 1912.

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