Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545234, here are decompositions:

  • 13 + 31545221 = 31545234
  • 23 + 31545211 = 31545234
  • 43 + 31545191 = 31545234
  • 53 + 31545181 = 31545234
  • 137 + 31545097 = 31545234
  • 151 + 31545083 = 31545234
  • 167 + 31545067 = 31545234
  • 173 + 31545061 = 31545234

Showing the first eight; more decompositions exist.
