Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616964, here are decompositions:

13 + 31616951 = 31616964
31 + 31616933 = 31616964
47 + 31616917 = 31616964
61 + 31616903 = 31616964
73 + 31616891 = 31616964
107 + 31616857 = 31616964
191 + 31616773 = 31616964
257 + 31616707 = 31616964

Showing the first eight; more decompositions exist.
