Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626808, here are decompositions:

11 + 31626797 = 31626808
41 + 31626767 = 31626808
251 + 31626557 = 31626808
347 + 31626461 = 31626808
401 + 31626407 = 31626808
419 + 31626389 = 31626808
431 + 31626377 = 31626808
449 + 31626359 = 31626808

Showing the first eight; more decompositions exist.
