Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626162, here are decompositions:

31 + 31626131 = 31626162
53 + 31626109 = 31626162
83 + 31626079 = 31626162
89 + 31626073 = 31626162
109 + 31626053 = 31626162
151 + 31626011 = 31626162
181 + 31625981 = 31626162
193 + 31625969 = 31626162

Showing the first eight; more decompositions exist.
