Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483656, here are decompositions:

7 + 31483649 = 31483656
59 + 31483597 = 31483656
73 + 31483583 = 31483656
79 + 31483577 = 31483656
103 + 31483553 = 31483656
107 + 31483549 = 31483656
109 + 31483547 = 31483656
163 + 31483493 = 31483656

Showing the first eight; more decompositions exist.
