Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483556, here are decompositions:

3 + 31483553 = 31483556
7 + 31483549 = 31483556
103 + 31483453 = 31483556
109 + 31483447 = 31483556
127 + 31483429 = 31483556
229 + 31483327 = 31483556
439 + 31483117 = 31483556
463 + 31483093 = 31483556

Showing the first eight; more decompositions exist.
