Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626964, here are decompositions:

71 + 31626893 = 31626964
107 + 31626857 = 31626964
137 + 31626827 = 31626964
167 + 31626797 = 31626964
197 + 31626767 = 31626964
401 + 31626563 = 31626964
431 + 31626533 = 31626964
503 + 31626461 = 31626964

Showing the first eight; more decompositions exist.
