Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617164, here are decompositions:

31 + 31617133 = 31617164
151 + 31617013 = 31617164
277 + 31616887 = 31617164
307 + 31616857 = 31617164
457 + 31616707 = 31617164
487 + 31616677 = 31617164
541 + 31616623 = 31617164
643 + 31616521 = 31617164

Showing the first eight; more decompositions exist.
