Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616802, here are decompositions:

29 + 31616773 = 31616802
53 + 31616749 = 31616802
73 + 31616729 = 31616802
109 + 31616693 = 31616802
131 + 31616671 = 31616802
179 + 31616623 = 31616802
199 + 31616603 = 31616802
223 + 31616579 = 31616802

Showing the first eight; more decompositions exist.
