Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616736, here are decompositions:

7 + 31616729 = 31616736
29 + 31616707 = 31616736
43 + 31616693 = 31616736
59 + 31616677 = 31616736
89 + 31616647 = 31616736
113 + 31616623 = 31616736
157 + 31616579 = 31616736
167 + 31616569 = 31616736

Showing the first eight; more decompositions exist.
