Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055478, here are decompositions:

  • 7 + 1055471 = 1055478
  • 41 + 1055437 = 1055478
  • 71 + 1055407 = 1055478
  • 79 + 1055399 = 1055478
  • 107 + 1055371 = 1055478
  • 131 + 1055347 = 1055478
  • 157 + 1055321 = 1055478
  • 211 + 1055267 = 1055478

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 5, 5478 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5478-05-01 (DMMYYYY (Euro, single-digit day))
  • 5478-10-05 (MMDYYYY (US, single-digit day))
  • 5478-05-10 (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 1,055,478 and was likely granted around 1912.

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