Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463556, here are decompositions:

23 + 31463533 = 31463556
29 + 31463527 = 31463556
37 + 31463519 = 31463556
67 + 31463489 = 31463556
73 + 31463483 = 31463556
79 + 31463477 = 31463556
97 + 31463459 = 31463556
127 + 31463429 = 31463556

Showing the first eight; more decompositions exist.
