Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626694, here are decompositions:

3 + 31626691 = 31626694
5 + 31626689 = 31626694
131 + 31626563 = 31626694
137 + 31626557 = 31626694
233 + 31626461 = 31626694
257 + 31626437 = 31626694
311 + 31626383 = 31626694
317 + 31626377 = 31626694

Showing the first eight; more decompositions exist.
