Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626472, here are decompositions:

11 + 31626461 = 31626472
83 + 31626389 = 31626472
89 + 31626383 = 31626472
113 + 31626359 = 31626472
149 + 31626323 = 31626472
239 + 31626233 = 31626472
263 + 31626209 = 31626472
281 + 31626191 = 31626472

Showing the first eight; more decompositions exist.
