Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626474, here are decompositions:

13 + 31626461 = 31626474
37 + 31626437 = 31626474
53 + 31626421 = 31626474
67 + 31626407 = 31626474
97 + 31626377 = 31626474
107 + 31626367 = 31626474
137 + 31626337 = 31626474
151 + 31626323 = 31626474

Showing the first eight; more decompositions exist.
