Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047072, here are decompositions:

  • 11 + 1047061 = 1047072
  • 29 + 1047043 = 1047072
  • 31 + 1047041 = 1047072
  • 41 + 1047031 = 1047072
  • 73 + 1046999 = 1047072
  • 79 + 1046993 = 1047072
  • 113 + 1046959 = 1047072
  • 139 + 1046933 = 1047072

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 7072 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7072-04-01 (DMMYYYY (Euro, single-digit day))
  • 7072-10-04 (MMDYYYY (US, single-digit day))
  • 7072-04-10 (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 1,047,072 and was likely granted around 1912.

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