Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617542, here are decompositions:

13 + 31617529 = 31617542
139 + 31617403 = 31617542
163 + 31617379 = 31617542
181 + 31617361 = 31617542
409 + 31617133 = 31617542
613 + 31616929 = 31617542
769 + 31616773 = 31617542
919 + 31616623 = 31617542

Showing the first eight; more decompositions exist.
