Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545264, here are decompositions:

  • 31 + 31545233 = 31545264
  • 43 + 31545221 = 31545264
  • 53 + 31545211 = 31545264
  • 73 + 31545191 = 31545264
  • 83 + 31545181 = 31545264
  • 167 + 31545097 = 31545264
  • 173 + 31545091 = 31545264
  • 181 + 31545083 = 31545264

Showing the first eight; more decompositions exist.
