Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621134, here are decompositions:

11 + 31621123 = 31621134
37 + 31621097 = 31621134
53 + 31621081 = 31621134
71 + 31621063 = 31621134
101 + 31621033 = 31621134
107 + 31621027 = 31621134
191 + 31620943 = 31621134
197 + 31620937 = 31621134

Showing the first eight; more decompositions exist.
