Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045400, here are decompositions:

  • 3 + 1045397 = 1045400
  • 7 + 1045393 = 1045400
  • 79 + 1045321 = 1045400
  • 127 + 1045273 = 1045400
  • 163 + 1045237 = 1045400
  • 271 + 1045129 = 1045400
  • 277 + 1045123 = 1045400
  • 283 + 1045117 = 1045400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 5400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5400-04-01 (DMMYYYY (Euro, single-digit day))
  • 5400-10-04 (MMDYYYY (US, single-digit day))
  • 5400-04-10 (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 1,045,400 and was likely granted around 1912.

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