Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023978, here are decompositions:

  • 5 + 1023973 = 1023978
  • 29 + 1023949 = 1023978
  • 31 + 1023947 = 1023978
  • 37 + 1023941 = 1023978
  • 107 + 1023871 = 1023978
  • 127 + 1023851 = 1023978
  • 139 + 1023839 = 1023978
  • 157 + 1023821 = 1023978

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 3978 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3978-02-01 (DMMYYYY (Euro, single-digit day))
  • 3978-10-02 (MMDYYYY (US, single-digit day))
  • 3978-02-10 (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 1,023,978 and was likely granted around 1912.

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