Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012638, here are decompositions:

  • 5 + 1012633 = 1012638
  • 7 + 1012631 = 1012638
  • 19 + 1012619 = 1012638
  • 37 + 1012601 = 1012638
  • 41 + 1012597 = 1012638
  • 47 + 1012591 = 1012638
  • 79 + 1012559 = 1012638
  • 89 + 1012549 = 1012638

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 2638 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2638-10-01 (MMDYYYY (US, single-digit day))
  • 2638-01-10 (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 1,012,638 and was likely granted around 1911.

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