Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620366, here are decompositions:

7 + 31620359 = 31620366
23 + 31620343 = 31620366
67 + 31620299 = 31620366
97 + 31620269 = 31620366
103 + 31620263 = 31620366
137 + 31620229 = 31620366
157 + 31620209 = 31620366
163 + 31620203 = 31620366

Showing the first eight; more decompositions exist.
