Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626552, here are decompositions:

5 + 31626547 = 31626552
19 + 31626533 = 31626552
53 + 31626499 = 31626552
59 + 31626493 = 31626552
71 + 31626481 = 31626552
131 + 31626421 = 31626552
163 + 31626389 = 31626552
193 + 31626359 = 31626552

Showing the first eight; more decompositions exist.
