Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015506, here are decompositions:

  • 5 + 1015501 = 1015506
  • 7 + 1015499 = 1015506
  • 43 + 1015463 = 1015506
  • 47 + 1015459 = 1015506
  • 53 + 1015453 = 1015506
  • 73 + 1015433 = 1015506
  • 83 + 1015423 = 1015506
  • 97 + 1015409 = 1015506

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 5506 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5506-10-01 (MMDYYYY (US, single-digit day))
  • 5506-01-10 (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 1,015,506 and was likely granted around 1911.

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