Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545338, here are decompositions:

  • 7 + 31545331 = 31545338
  • 127 + 31545211 = 31545338
  • 157 + 31545181 = 31545338
  • 241 + 31545097 = 31545338
  • 271 + 31545067 = 31545338
  • 277 + 31545061 = 31545338
  • 337 + 31545001 = 31545338
  • 397 + 31544941 = 31545338

Showing the first eight; more decompositions exist.
