Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463566, here are decompositions:

47 + 31463519 = 31463566
59 + 31463507 = 31463566
83 + 31463483 = 31463566
89 + 31463477 = 31463566
107 + 31463459 = 31463566
137 + 31463429 = 31463566
179 + 31463387 = 31463566
317 + 31463249 = 31463566

Showing the first eight; more decompositions exist.
