Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476822, here are decompositions:

23 + 31476799 = 31476822
79 + 31476743 = 31476822
89 + 31476733 = 31476822
131 + 31476691 = 31476822
191 + 31476631 = 31476822
199 + 31476623 = 31476822
211 + 31476611 = 31476822
229 + 31476593 = 31476822

Showing the first eight; more decompositions exist.
