Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545352, here are decompositions:

  • 23 + 31545329 = 31545352
  • 29 + 31545323 = 31545352
  • 53 + 31545299 = 31545352
  • 131 + 31545221 = 31545352
  • 233 + 31545119 = 31545352
  • 269 + 31545083 = 31545352
  • 383 + 31544969 = 31545352
  • 389 + 31544963 = 31545352

Showing the first eight; more decompositions exist.
