Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045478, here are decompositions:

  • 67 + 1045411 = 1045478
  • 157 + 1045321 = 1045478
  • 241 + 1045237 = 1045478
  • 349 + 1045129 = 1045478
  • 367 + 1045111 = 1045478
  • 397 + 1045081 = 1045478
  • 457 + 1045021 = 1045478
  • 547 + 1044931 = 1045478

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 5478 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5478-04-01 (DMMYYYY (Euro, single-digit day))
  • 5478-10-04 (MMDYYYY (US, single-digit day))
  • 5478-04-10 (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 1,045,478 and was likely granted around 1912.

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