Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623224, here are decompositions:

  • 13 + 31623211 = 31623224
  • 43 + 31623181 = 31623224
  • 103 + 31623121 = 31623224
  • 163 + 31623061 = 31623224
  • 277 + 31622947 = 31623224
  • 331 + 31622893 = 31623224
  • 421 + 31622803 = 31623224
  • 541 + 31622683 = 31623224

Showing the first eight; more decompositions exist.
