Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523134, here are decompositions:

3 + 31523131 = 31523134
23 + 31523111 = 31523134
53 + 31523081 = 31523134
107 + 31523027 = 31523134
113 + 31523021 = 31523134
131 + 31523003 = 31523134
173 + 31522961 = 31523134
197 + 31522937 = 31523134

Showing the first eight; more decompositions exist.
