Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626510, here are decompositions:

11 + 31626499 = 31626510
17 + 31626493 = 31626510
29 + 31626481 = 31626510
73 + 31626437 = 31626510
89 + 31626421 = 31626510
103 + 31626407 = 31626510
127 + 31626383 = 31626510
151 + 31626359 = 31626510

Showing the first eight; more decompositions exist.
