Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020242, here are decompositions:

  • 19 + 1020223 = 1020242
  • 79 + 1020163 = 1020242
  • 163 + 1020079 = 1020242
  • 193 + 1020049 = 1020242
  • 199 + 1020043 = 1020242
  • 229 + 1020013 = 1020242
  • 241 + 1020001 = 1020242
  • 271 + 1019971 = 1020242

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 0242 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0242-02-01 (DMMYYYY (Euro, single-digit day))
  • 0242-10-02 (MMDYYYY (US, single-digit day))
  • 0242-02-10 (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 1,020,242 and was likely granted around 1911.

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