Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616152, here are decompositions:

3 + 31616149 = 31616152
23 + 31616129 = 31616152
83 + 31616069 = 31616152
131 + 31616021 = 31616152
173 + 31615979 = 31616152
179 + 31615973 = 31616152
233 + 31615919 = 31616152
389 + 31615763 = 31616152

Showing the first eight; more decompositions exist.
