Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617448, here are decompositions:

17 + 31617431 = 31617448
41 + 31617407 = 31617448
167 + 31617281 = 31617448
179 + 31617269 = 31617448
197 + 31617251 = 31617448
281 + 31617167 = 31617448
347 + 31617101 = 31617448
419 + 31617029 = 31617448

Showing the first eight; more decompositions exist.
