Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616270, here are decompositions:

13 + 31616257 = 31616270
19 + 31616251 = 31616270
97 + 31616173 = 31616270
157 + 31616113 = 31616270
211 + 31616059 = 31616270
223 + 31616047 = 31616270
229 + 31616041 = 31616270
271 + 31615999 = 31616270

Showing the first eight; more decompositions exist.
