Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626800, here are decompositions:

3 + 31626797 = 31626800
13 + 31626787 = 31626800
109 + 31626691 = 31626800
181 + 31626619 = 31626800
193 + 31626607 = 31626800
211 + 31626589 = 31626800
229 + 31626571 = 31626800
307 + 31626493 = 31626800

Showing the first eight; more decompositions exist.
