Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015072, here are decompositions:

  • 5 + 1015067 = 1015072
  • 11 + 1015061 = 1015072
  • 29 + 1015043 = 1015072
  • 83 + 1014989 = 1015072
  • 131 + 1014941 = 1015072
  • 239 + 1014833 = 1015072
  • 251 + 1014821 = 1015072
  • 293 + 1014779 = 1015072

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 5072 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5072-10-01 (MMDYYYY (US, single-digit day))
  • 5072-01-10 (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 1,015,072 and was likely granted around 1911.

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