Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018970, here are decompositions:

  • 3 + 1018967 = 1018970
  • 13 + 1018957 = 1018970
  • 67 + 1018903 = 1018970
  • 97 + 1018873 = 1018970
  • 157 + 1018813 = 1018970
  • 163 + 1018807 = 1018970
  • 181 + 1018789 = 1018970
  • 193 + 1018777 = 1018970

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 8970 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8970-10-01 (MMDYYYY (US, single-digit day))
  • 8970-01-10 (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 1,018,970 and was likely granted around 1911.

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