Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622912, here are decompositions:

  • 19 + 31622893 = 31622912
  • 31 + 31622881 = 31622912
  • 103 + 31622809 = 31622912
  • 109 + 31622803 = 31622912
  • 199 + 31622713 = 31622912
  • 229 + 31622683 = 31622912
  • 241 + 31622671 = 31622912
  • 271 + 31622641 = 31622912

Showing the first eight; more decompositions exist.
