Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528078, here are decompositions:

  • 11 + 31528067 = 31528078
  • 41 + 31528037 = 31528078
  • 59 + 31528019 = 31528078
  • 137 + 31527941 = 31528078
  • 191 + 31527887 = 31528078
  • 251 + 31527827 = 31528078
  • 389 + 31527689 = 31528078
  • 401 + 31527677 = 31528078

Showing the first eight; more decompositions exist.
