Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616534, here are decompositions:

13 + 31616521 = 31616534
277 + 31616257 = 31616534
283 + 31616251 = 31616534
421 + 31616113 = 31616534
487 + 31616047 = 31616534
541 + 31615993 = 31616534
613 + 31615921 = 31616534
643 + 31615891 = 31616534

Showing the first eight; more decompositions exist.
