Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015742, here are decompositions:

  • 3 + 1015739 = 1015742
  • 19 + 1015723 = 1015742
  • 139 + 1015603 = 1015742
  • 181 + 1015561 = 1015742
  • 193 + 1015549 = 1015742
  • 241 + 1015501 = 1015742
  • 271 + 1015471 = 1015742
  • 283 + 1015459 = 1015742

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 5742 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5742-10-01 (MMDYYYY (US, single-digit day))
  • 5742-01-10 (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 1,015,742 and was likely granted around 1911.

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