Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626036, here are decompositions:

17 + 31626019 = 31626036
67 + 31625969 = 31626036
73 + 31625963 = 31626036
83 + 31625953 = 31626036
97 + 31625939 = 31626036
193 + 31625843 = 31626036
229 + 31625807 = 31626036
257 + 31625779 = 31626036

Showing the first eight; more decompositions exist.
