Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490050, here are decompositions:

  • 17 + 490033 = 490050
  • 19 + 490031 = 490050
  • 31 + 490019 = 490050
  • 47 + 490003 = 490050
  • 61 + 489989 = 490050
  • 73 + 489977 = 490050
  • 89 + 489961 = 490050
  • 107 + 489943 = 490050

Showing the first eight; more decompositions exist.

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 490,050 and was likely granted around 1892.

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