Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016428, here are decompositions:

  • 5 + 1016423 = 1016428
  • 29 + 1016399 = 1016428
  • 71 + 1016357 = 1016428
  • 89 + 1016339 = 1016428
  • 191 + 1016237 = 1016428
  • 197 + 1016231 = 1016428
  • 227 + 1016201 = 1016428
  • 269 + 1016159 = 1016428

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 6428 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 6428-10-01 (MMDYYYY (US, single-digit day))
  • 6428-01-10 (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 1,016,428 and was likely granted around 1911.

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