Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626558, here are decompositions:

11 + 31626547 = 31626558
59 + 31626499 = 31626558
97 + 31626461 = 31626558
137 + 31626421 = 31626558
151 + 31626407 = 31626558
181 + 31626377 = 31626558
191 + 31626367 = 31626558
199 + 31626359 = 31626558

Showing the first eight; more decompositions exist.
