Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626484, here are decompositions:

3 + 31626481 = 31626484
23 + 31626461 = 31626484
47 + 31626437 = 31626484
101 + 31626383 = 31626484
107 + 31626377 = 31626484
251 + 31626233 = 31626484
293 + 31626191 = 31626484
317 + 31626167 = 31626484

Showing the first eight; more decompositions exist.
