Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626018, here are decompositions:

7 + 31626011 = 31626018
31 + 31625987 = 31626018
37 + 31625981 = 31626018
79 + 31625939 = 31626018
101 + 31625917 = 31626018
107 + 31625911 = 31626018
197 + 31625821 = 31626018
199 + 31625819 = 31626018

Showing the first eight; more decompositions exist.
