Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047478, here are decompositions:

  • 11 + 1047467 = 1047478
  • 59 + 1047419 = 1047478
  • 137 + 1047341 = 1047478
  • 167 + 1047311 = 1047478
  • 197 + 1047281 = 1047478
  • 239 + 1047239 = 1047478
  • 281 + 1047197 = 1047478
  • 347 + 1047131 = 1047478

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 7478 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7478-04-01 (DMMYYYY (Euro, single-digit day))
  • 7478-10-04 (MMDYYYY (US, single-digit day))
  • 7478-04-10 (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 1,047,478 and was likely granted around 1912.

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