Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550026, here are decompositions:

  • 5 + 31550021 = 31550026
  • 47 + 31549979 = 31550026
  • 59 + 31549967 = 31550026
  • 107 + 31549919 = 31550026
  • 197 + 31549829 = 31550026
  • 227 + 31549799 = 31550026
  • 293 + 31549733 = 31550026
  • 359 + 31549667 = 31550026

Showing the first eight; more decompositions exist.
