Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042556, here are decompositions:

  • 37 + 1042519 = 1042556
  • 157 + 1042399 = 1042556
  • 199 + 1042357 = 1042556
  • 223 + 1042333 = 1042556
  • 283 + 1042273 = 1042556
  • 313 + 1042243 = 1042556
  • 373 + 1042183 = 1042556
  • 433 + 1042123 = 1042556

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 2556 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2556-04-01 (DMMYYYY (Euro, single-digit day))
  • 2556-10-04 (MMDYYYY (US, single-digit day))
  • 2556-04-10 (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 1,042,556 and was likely granted around 1912.

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