Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624356, here are decompositions:

  • 7 + 31624349 = 31624356
  • 13 + 31624343 = 31624356
  • 17 + 31624339 = 31624356
  • 19 + 31624337 = 31624356
  • 73 + 31624283 = 31624356
  • 79 + 31624277 = 31624356
  • 139 + 31624217 = 31624356
  • 227 + 31624129 = 31624356

Showing the first eight; more decompositions exist.
