Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015618, here are decompositions:

  • 17 + 1015601 = 1015618
  • 47 + 1015571 = 1015618
  • 59 + 1015559 = 1015618
  • 101 + 1015517 = 1015618
  • 137 + 1015481 = 1015618
  • 167 + 1015451 = 1015618
  • 251 + 1015367 = 1015618
  • 257 + 1015361 = 1015618

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 5618 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5618-10-01 (MMDYYYY (US, single-digit day))
  • 5618-01-10 (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 1,015,618 and was likely granted around 1911.

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