Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626014, here are decompositions:

3 + 31626011 = 31626014
61 + 31625953 = 31626014
97 + 31625917 = 31626014
103 + 31625911 = 31626014
193 + 31625821 = 31626014
241 + 31625773 = 31626014
283 + 31625731 = 31626014
367 + 31625647 = 31626014

Showing the first eight; more decompositions exist.
