Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015042, here are decompositions:

  • 3 + 1015039 = 1015042
  • 53 + 1014989 = 1015042
  • 89 + 1014953 = 1015042
  • 101 + 1014941 = 1015042
  • 173 + 1014869 = 1015042
  • 179 + 1014863 = 1015042
  • 263 + 1014779 = 1015042
  • 293 + 1014749 = 1015042

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 5042 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5042-10-01 (MMDYYYY (US, single-digit day))
  • 5042-01-10 (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 1,015,042 and was likely granted around 1911.

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