Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025000, here are decompositions:

  • 3 + 1024997 = 1025000
  • 13 + 1024987 = 1025000
  • 37 + 1024963 = 1025000
  • 43 + 1024957 = 1025000
  • 61 + 1024939 = 1025000
  • 79 + 1024921 = 1025000
  • 157 + 1024843 = 1025000
  • 271 + 1024729 = 1025000

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 5000 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5000-02-01 (DMMYYYY (Euro, single-digit day))
  • 5000-10-02 (MMDYYYY (US, single-digit day))
  • 5000-02-10 (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 1,025,000 and was likely granted around 1912.

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