Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617952, here are decompositions:

11 + 31617941 = 31617952
53 + 31617899 = 31617952
89 + 31617863 = 31617952
239 + 31617713 = 31617952
263 + 31617689 = 31617952
293 + 31617659 = 31617952
389 + 31617563 = 31617952
419 + 31617533 = 31617952

Showing the first eight; more decompositions exist.
