Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051390, here are decompositions:

  • 17 + 1051373 = 1051390
  • 71 + 1051319 = 1051390
  • 89 + 1051301 = 1051390
  • 107 + 1051283 = 1051390
  • 113 + 1051277 = 1051390
  • 233 + 1051157 = 1051390
  • 239 + 1051151 = 1051390
  • 251 + 1051139 = 1051390

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 5, 1390 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1390-05-01 (DMMYYYY (Euro, single-digit day))
  • 1390-10-05 (MMDYYYY (US, single-digit day))
  • 1390-05-10 (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 1,051,390 and was likely granted around 1912.

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