Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626994, here are decompositions:

17 + 31626977 = 31626994
101 + 31626893 = 31626994
137 + 31626857 = 31626994
167 + 31626827 = 31626994
197 + 31626797 = 31626994
227 + 31626767 = 31626994
431 + 31626563 = 31626994
461 + 31626533 = 31626994

Showing the first eight; more decompositions exist.
