Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028156, here are decompositions:

  • 7 + 1028149 = 1028156
  • 43 + 1028113 = 1028156
  • 67 + 1028089 = 1028156
  • 109 + 1028047 = 1028156
  • 127 + 1028029 = 1028156
  • 139 + 1028017 = 1028156
  • 373 + 1027783 = 1028156
  • 379 + 1027777 = 1028156

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 8156 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8156-02-01 (DMMYYYY (Euro, single-digit day))
  • 8156-10-02 (MMDYYYY (US, single-digit day))
  • 8156-02-10 (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 1,028,156 and was likely granted around 1912.

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