Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523118, here are decompositions:

5 + 31523113 = 31523118
7 + 31523111 = 31523118
19 + 31523099 = 31523118
37 + 31523081 = 31523118
97 + 31523021 = 31523118
131 + 31522987 = 31523118
139 + 31522979 = 31523118
157 + 31522961 = 31523118

Showing the first eight; more decompositions exist.
