Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999242, here are decompositions:

  • 3 + 999239 = 999242
  • 43 + 999199 = 999242
  • 61 + 999181 = 999242
  • 73 + 999169 = 999242
  • 109 + 999133 = 999242
  • 151 + 999091 = 999242
  • 193 + 999049 = 999242
  • 199 + 999043 = 999242

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 999,242 and was likely granted around 1911.

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