Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013978, here are decompositions:

  • 79 + 1013899 = 1013978
  • 127 + 1013851 = 1013978
  • 139 + 1013839 = 1013978
  • 151 + 1013827 = 1013978
  • 211 + 1013767 = 1013978
  • 307 + 1013671 = 1013978
  • 337 + 1013641 = 1013978
  • 349 + 1013629 = 1013978

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 3978 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3978-10-01 (MMDYYYY (US, single-digit day))
  • 3978-01-10 (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 1,013,978 and was likely granted around 1911.

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