Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018206, here are decompositions:

  • 5 + 1018201 = 1018206
  • 29 + 1018177 = 1018206
  • 83 + 1018123 = 1018206
  • 97 + 1018109 = 1018206
  • 109 + 1018097 = 1018206
  • 149 + 1018057 = 1018206
  • 199 + 1018007 = 1018206
  • 283 + 1017923 = 1018206

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 8206 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8206-10-01 (MMDYYYY (US, single-digit day))
  • 8206-01-10 (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 1,018,206 and was likely granted around 1911.

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