Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626066, here are decompositions:

13 + 31626053 = 31626066
47 + 31626019 = 31626066
79 + 31625987 = 31626066
97 + 31625969 = 31626066
103 + 31625963 = 31626066
113 + 31625953 = 31626066
127 + 31625939 = 31626066
149 + 31625917 = 31626066

Showing the first eight; more decompositions exist.
