Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522134, here are decompositions:

5 + 31522129 = 31522134
31 + 31522103 = 31522134
43 + 31522091 = 31522134
73 + 31522061 = 31522134
113 + 31522021 = 31522134
157 + 31521977 = 31522134
181 + 31521953 = 31522134
251 + 31521883 = 31522134

Showing the first eight; more decompositions exist.
