Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626090, here are decompositions:

11 + 31626079 = 31626090
17 + 31626073 = 31626090
37 + 31626053 = 31626090
71 + 31626019 = 31626090
79 + 31626011 = 31626090
103 + 31625987 = 31626090
109 + 31625981 = 31626090
127 + 31625963 = 31626090

Showing the first eight; more decompositions exist.
