Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626804, here are decompositions:

7 + 31626797 = 31626804
17 + 31626787 = 31626804
37 + 31626767 = 31626804
113 + 31626691 = 31626804
137 + 31626667 = 31626804
197 + 31626607 = 31626804
233 + 31626571 = 31626804
241 + 31626563 = 31626804

Showing the first eight; more decompositions exist.
