Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015664, here are decompositions:

  • 3 + 1015661 = 1015664
  • 37 + 1015627 = 1015664
  • 61 + 1015603 = 1015664
  • 103 + 1015561 = 1015664
  • 157 + 1015507 = 1015664
  • 163 + 1015501 = 1015664
  • 193 + 1015471 = 1015664
  • 211 + 1015453 = 1015664

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 5664 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5664-10-01 (MMDYYYY (US, single-digit day))
  • 5664-01-10 (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 1,015,664 and was likely granted around 1911.

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