Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024742, here are decompositions:

  • 13 + 1024729 = 1024742
  • 31 + 1024711 = 1024742
  • 73 + 1024669 = 1024742
  • 79 + 1024663 = 1024742
  • 109 + 1024633 = 1024742
  • 151 + 1024591 = 1024742
  • 163 + 1024579 = 1024742
  • 331 + 1024411 = 1024742

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 4742 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 4742-02-01 (DMMYYYY (Euro, single-digit day))
  • 4742-10-02 (MMDYYYY (US, single-digit day))
  • 4742-02-10 (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 1,024,742 and was likely granted around 1912.

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