Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015156, here are decompositions:

  • 17 + 1015139 = 1015156
  • 29 + 1015127 = 1015156
  • 59 + 1015097 = 1015156
  • 83 + 1015073 = 1015156
  • 89 + 1015067 = 1015156
  • 113 + 1015043 = 1015156
  • 167 + 1014989 = 1015156
  • 269 + 1014887 = 1015156

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 5156 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5156-10-01 (MMDYYYY (US, single-digit day))
  • 5156-01-10 (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 1,015,156 and was likely granted around 1911.

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