Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617458, here are decompositions:

79 + 31617379 = 31617458
97 + 31617361 = 31617458
277 + 31617181 = 31617458
409 + 31617049 = 31617458
541 + 31616917 = 31617458
571 + 31616887 = 31617458
601 + 31616857 = 31617458
619 + 31616839 = 31617458

Showing the first eight; more decompositions exist.
