Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005190, here are decompositions:

  • 3 + 1005187 = 1005190
  • 29 + 1005161 = 1005190
  • 47 + 1005143 = 1005190
  • 59 + 1005131 = 1005190
  • 83 + 1005107 = 1005190
  • 89 + 1005101 = 1005190
  • 149 + 1005041 = 1005190
  • 227 + 1004963 = 1005190

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 1,005,190 and was likely granted around 1911.

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