Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617546, here are decompositions:

13 + 31617533 = 31617546
17 + 31617529 = 31617546
43 + 31617503 = 31617546
53 + 31617493 = 31617546
89 + 31617457 = 31617546
97 + 31617449 = 31617546
137 + 31617409 = 31617546
139 + 31617407 = 31617546

Showing the first eight; more decompositions exist.
