Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545454, here are decompositions:

  • 47 + 31545407 = 31545454
  • 53 + 31545401 = 31545454
  • 131 + 31545323 = 31545454
  • 137 + 31545317 = 31545454
  • 167 + 31545287 = 31545454
  • 233 + 31545221 = 31545454
  • 263 + 31545191 = 31545454
  • 431 + 31545023 = 31545454

Showing the first eight; more decompositions exist.
