Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463568, here are decompositions:

41 + 31463527 = 31463568
61 + 31463507 = 31463568
79 + 31463489 = 31463568
109 + 31463459 = 31463568
139 + 31463429 = 31463568
179 + 31463389 = 31463568
181 + 31463387 = 31463568
239 + 31463329 = 31463568

Showing the first eight; more decompositions exist.
