Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523224, here are decompositions:

3 + 31523221 = 31523224
17 + 31523207 = 31523224
23 + 31523201 = 31523224
113 + 31523111 = 31523224
197 + 31523027 = 31523224
263 + 31522961 = 31523224
401 + 31522823 = 31523224
641 + 31522583 = 31523224

Showing the first eight; more decompositions exist.
