Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526250, here are decompositions:

  • 11 + 31526239 = 31526250
  • 23 + 31526227 = 31526250
  • 29 + 31526221 = 31526250
  • 37 + 31526213 = 31526250
  • 43 + 31526207 = 31526250
  • 53 + 31526197 = 31526250
  • 59 + 31526191 = 31526250
  • 61 + 31526189 = 31526250

Showing the first eight; more decompositions exist.
