Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047240, here are decompositions:

  • 11 + 1047229 = 1047240
  • 41 + 1047199 = 1047240
  • 43 + 1047197 = 1047240
  • 67 + 1047173 = 1047240
  • 83 + 1047157 = 1047240
  • 101 + 1047139 = 1047240
  • 107 + 1047133 = 1047240
  • 109 + 1047131 = 1047240

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 7240 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7240-04-01 (DMMYYYY (Euro, single-digit day))
  • 7240-10-04 (MMDYYYY (US, single-digit day))
  • 7240-04-10 (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 1,047,240 and was likely granted around 1912.

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