Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617434, here are decompositions:

3 + 31617431 = 31617434
31 + 31617403 = 31617434
61 + 31617373 = 31617434
73 + 31617361 = 31617434
151 + 31617283 = 31617434
181 + 31617253 = 31617434
421 + 31617013 = 31617434
547 + 31616887 = 31617434

Showing the first eight; more decompositions exist.
