Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015500, here are decompositions:

  • 19 + 1015481 = 1015500
  • 29 + 1015471 = 1015500
  • 37 + 1015463 = 1015500
  • 41 + 1015459 = 1015500
  • 47 + 1015453 = 1015500
  • 67 + 1015433 = 1015500
  • 97 + 1015403 = 1015500
  • 131 + 1015369 = 1015500

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 5500 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5500-10-01 (MMDYYYY (US, single-digit day))
  • 5500-01-10 (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 1,015,500 and was likely granted around 1911.

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