Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019998, here are decompositions:

  • 71 + 1019927 = 1019998
  • 137 + 1019861 = 1019998
  • 149 + 1019849 = 1019998
  • 179 + 1019819 = 1019998
  • 197 + 1019801 = 1019998
  • 227 + 1019771 = 1019998
  • 251 + 1019747 = 1019998
  • 257 + 1019741 = 1019998

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 9998 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 9998-10-01 (MMDYYYY (US, single-digit day))
  • 9998-01-10 (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 1,019,998 and was likely granted around 1911.

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