Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616004, here are decompositions:

5 + 31615999 = 31616004
11 + 31615993 = 31616004
31 + 31615973 = 31616004
53 + 31615951 = 31616004
83 + 31615921 = 31616004
113 + 31615891 = 31616004
157 + 31615847 = 31616004
197 + 31615807 = 31616004

Showing the first eight; more decompositions exist.
