Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528926, here are decompositions:

  • 17 + 31528909 = 31528926
  • 73 + 31528853 = 31528926
  • 83 + 31528843 = 31528926
  • 103 + 31528823 = 31528926
  • 113 + 31528813 = 31528926
  • 197 + 31528729 = 31528926
  • 229 + 31528697 = 31528926
  • 257 + 31528669 = 31528926

Showing the first eight; more decompositions exist.
