Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626132, here are decompositions:

23 + 31626109 = 31626132
53 + 31626079 = 31626132
59 + 31626073 = 31626132
79 + 31626053 = 31626132
113 + 31626019 = 31626132
151 + 31625981 = 31626132
163 + 31625969 = 31626132
179 + 31625953 = 31626132

Showing the first eight; more decompositions exist.
