Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626556, here are decompositions:

23 + 31626533 = 31626556
149 + 31626407 = 31626556
167 + 31626389 = 31626556
173 + 31626383 = 31626556
179 + 31626377 = 31626556
197 + 31626359 = 31626556
233 + 31626323 = 31626556
347 + 31626209 = 31626556

Showing the first eight; more decompositions exist.
