Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616712, here are decompositions:

5 + 31616707 = 31616712
19 + 31616693 = 31616712
41 + 31616671 = 31616712
89 + 31616623 = 31616712
109 + 31616603 = 31616712
151 + 31616561 = 31616712
173 + 31616539 = 31616712
191 + 31616521 = 31616712

Showing the first eight; more decompositions exist.
