Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045480, here are decompositions:

  • 11 + 1045469 = 1045480
  • 53 + 1045427 = 1045480
  • 71 + 1045409 = 1045480
  • 83 + 1045397 = 1045480
  • 89 + 1045391 = 1045480
  • 113 + 1045367 = 1045480
  • 131 + 1045349 = 1045480
  • 173 + 1045307 = 1045480

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 5480 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5480-04-01 (DMMYYYY (Euro, single-digit day))
  • 5480-10-04 (MMDYYYY (US, single-digit day))
  • 5480-04-10 (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 1,045,480 and was likely granted around 1912.

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