Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616164, here are decompositions:

131 + 31616033 = 31616164
191 + 31615973 = 31616164
317 + 31615847 = 31616164
401 + 31615763 = 31616164
761 + 31615403 = 31616164
773 + 31615391 = 31616164
821 + 31615343 = 31616164
947 + 31615217 = 31616164

Showing the first eight; more decompositions exist.
