Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016280, here are decompositions:

  • 17 + 1016263 = 1016280
  • 43 + 1016237 = 1016280
  • 53 + 1016227 = 1016280
  • 59 + 1016221 = 1016280
  • 79 + 1016201 = 1016280
  • 107 + 1016173 = 1016280
  • 127 + 1016153 = 1016280
  • 137 + 1016143 = 1016280

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 6280 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 6280-10-01 (MMDYYYY (US, single-digit day))
  • 6280-01-10 (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 1,016,280 and was likely granted around 1911.

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