Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012400, here are decompositions:

  • 3 + 1012397 = 1012400
  • 31 + 1012369 = 1012400
  • 79 + 1012321 = 1012400
  • 139 + 1012261 = 1012400
  • 199 + 1012201 = 1012400
  • 211 + 1012189 = 1012400
  • 229 + 1012171 = 1012400
  • 241 + 1012159 = 1012400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 2400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2400-10-01 (MMDYYYY (US, single-digit day))
  • 2400-01-10 (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 1,012,400 and was likely granted around 1911.

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