Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527256, here are decompositions:

  • 3 + 31527253 = 31527256
  • 23 + 31527233 = 31527256
  • 83 + 31527173 = 31527256
  • 107 + 31527149 = 31527256
  • 113 + 31527143 = 31527256
  • 149 + 31527107 = 31527256
  • 179 + 31527077 = 31527256
  • 239 + 31527017 = 31527256

Showing the first eight; more decompositions exist.
