Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019478, here are decompositions:

  • 7 + 1019471 = 1019478
  • 11 + 1019467 = 1019478
  • 29 + 1019449 = 1019478
  • 67 + 1019411 = 1019478
  • 79 + 1019399 = 1019478
  • 101 + 1019377 = 1019478
  • 127 + 1019351 = 1019478
  • 139 + 1019339 = 1019478

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 1, 9478 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 9478-10-01 (MMDYYYY (US, single-digit day))
  • 9478-01-10 (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 1,019,478 and was likely granted around 1911.

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