Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523124, here are decompositions:

5 + 31523119 = 31523124
11 + 31523113 = 31523124
13 + 31523111 = 31523124
43 + 31523081 = 31523124
71 + 31523053 = 31523124
97 + 31523027 = 31523124
103 + 31523021 = 31523124
137 + 31522987 = 31523124

Showing the first eight; more decompositions exist.
