Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038730, here are decompositions:

  • 3 + 1038727 = 1038730
  • 23 + 1038707 = 1038730
  • 41 + 1038689 = 1038730
  • 59 + 1038671 = 1038730
  • 101 + 1038629 = 1038730
  • 107 + 1038623 = 1038730
  • 113 + 1038617 = 1038730
  • 131 + 1038599 = 1038730

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 3, 8730 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8730-03-01 (DMMYYYY (Euro, single-digit day))
  • 8730-10-03 (MMDYYYY (US, single-digit day))
  • 8730-03-10 (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 1,038,730 and was likely granted around 1912.

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