Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008142, here are decompositions:

  • 11 + 1008131 = 1008142
  • 41 + 1008101 = 1008142
  • 101 + 1008041 = 1008142
  • 251 + 1007891 = 1008142
  • 269 + 1007873 = 1008142
  • 281 + 1007861 = 1008142
  • 353 + 1007789 = 1008142
  • 383 + 1007759 = 1008142

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 1,008,142 and was likely granted around 1911.

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