Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050728, here are decompositions:

  • 97 + 1050631 = 1050728
  • 271 + 1050457 = 1050728
  • 277 + 1050451 = 1050728
  • 307 + 1050421 = 1050728
  • 337 + 1050391 = 1050728
  • 379 + 1050349 = 1050728
  • 397 + 1050331 = 1050728
  • 421 + 1050307 = 1050728

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 5, 0728 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0728-05-01 (DMMYYYY (Euro, single-digit day))
  • 0728-10-05 (MMDYYYY (US, single-digit day))
  • 0728-05-10 (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 1,050,728 and was likely granted around 1912.

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