Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472038, here are decompositions:

  • 47 + 31471991 = 31472038
  • 71 + 31471967 = 31472038
  • 131 + 31471907 = 31472038
  • 137 + 31471901 = 31472038
  • 239 + 31471799 = 31472038
  • 251 + 31471787 = 31472038
  • 401 + 31471637 = 31472038
  • 461 + 31471577 = 31472038

Showing the first eight; more decompositions exist.
