Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543224, here are decompositions:

  • 5 + 31543219 = 31543224
  • 7 + 31543217 = 31543224
  • 17 + 31543207 = 31543224
  • 43 + 31543181 = 31543224
  • 61 + 31543163 = 31543224
  • 157 + 31543067 = 31543224
  • 233 + 31542991 = 31543224
  • 257 + 31542967 = 31543224

Showing the first eight; more decompositions exist.
