Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617038, here are decompositions:

109 + 31616929 = 31617038
151 + 31616887 = 31617038
181 + 31616857 = 31617038
199 + 31616839 = 31617038
331 + 31616707 = 31617038
367 + 31616671 = 31617038
499 + 31616539 = 31617038
619 + 31616419 = 31617038

Showing the first eight; more decompositions exist.
