Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626582, here are decompositions:

11 + 31626571 = 31626582
19 + 31626563 = 31626582
83 + 31626499 = 31626582
89 + 31626493 = 31626582
101 + 31626481 = 31626582
193 + 31626389 = 31626582
199 + 31626383 = 31626582
223 + 31626359 = 31626582

Showing the first eight; more decompositions exist.
