Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617472, here are decompositions:

11 + 31617461 = 31617472
23 + 31617449 = 31617472
41 + 31617431 = 31617472
59 + 31617413 = 31617472
101 + 31617371 = 31617472
179 + 31617293 = 31617472
191 + 31617281 = 31617472
233 + 31617239 = 31617472

Showing the first eight; more decompositions exist.
