Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626252, here are decompositions:

5 + 31626247 = 31626252
19 + 31626233 = 31626252
23 + 31626229 = 31626252
43 + 31626209 = 31626252
59 + 31626193 = 31626252
61 + 31626191 = 31626252
173 + 31626079 = 31626252
179 + 31626073 = 31626252

Showing the first eight; more decompositions exist.
