Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011870, here are decompositions:

  • 43 + 1011827 = 1011870
  • 53 + 1011817 = 1011870
  • 71 + 1011799 = 1011870
  • 73 + 1011797 = 1011870
  • 107 + 1011763 = 1011870
  • 137 + 1011733 = 1011870
  • 151 + 1011719 = 1011870
  • 173 + 1011697 = 1011870

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 1870 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 1870-10-01 (MMDYYYY (US, single-digit day))
  • 1870-01-10 (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 1,011,870 and was likely granted around 1911.

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