Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617424, here are decompositions:

11 + 31617413 = 31617424
17 + 31617407 = 31617424
53 + 31617371 = 31617424
131 + 31617293 = 31617424
173 + 31617251 = 31617424
257 + 31617167 = 31617424
347 + 31617077 = 31617424
401 + 31617023 = 31617424

Showing the first eight; more decompositions exist.
