Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616752, here are decompositions:

3 + 31616749 = 31616752
5 + 31616747 = 31616752
23 + 31616729 = 31616752
59 + 31616693 = 31616752
149 + 31616603 = 31616752
173 + 31616579 = 31616752
191 + 31616561 = 31616752
359 + 31616393 = 31616752

Showing the first eight; more decompositions exist.
