Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015450, here are decompositions:

  • 17 + 1015433 = 1015450
  • 41 + 1015409 = 1015450
  • 47 + 1015403 = 1015450
  • 83 + 1015367 = 1015450
  • 89 + 1015361 = 1015450
  • 101 + 1015349 = 1015450
  • 173 + 1015277 = 1015450
  • 251 + 1015199 = 1015450

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 5450 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5450-10-01 (MMDYYYY (US, single-digit day))
  • 5450-01-10 (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 1,015,450 and was likely granted around 1911.

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