Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483566, here are decompositions:

13 + 31483553 = 31483566
17 + 31483549 = 31483566
19 + 31483547 = 31483566
73 + 31483493 = 31483566
97 + 31483469 = 31483566
109 + 31483457 = 31483566
113 + 31483453 = 31483566
137 + 31483429 = 31483566

Showing the first eight; more decompositions exist.
