Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626498, here are decompositions:

5 + 31626493 = 31626498
17 + 31626481 = 31626498
37 + 31626461 = 31626498
61 + 31626437 = 31626498
109 + 31626389 = 31626498
131 + 31626367 = 31626498
139 + 31626359 = 31626498
251 + 31626247 = 31626498

Showing the first eight; more decompositions exist.
