Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616132, here are decompositions:

3 + 31616129 = 31616132
19 + 31616113 = 31616132
73 + 31616059 = 31616132
109 + 31616023 = 31616132
139 + 31615993 = 31616132
181 + 31615951 = 31616132
211 + 31615921 = 31616132
241 + 31615891 = 31616132

Showing the first eight; more decompositions exist.
