Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616992, here are decompositions:

5 + 31616987 = 31616992
41 + 31616951 = 31616992
59 + 31616933 = 31616992
89 + 31616903 = 31616992
101 + 31616891 = 31616992
263 + 31616729 = 31616992
389 + 31616603 = 31616992
431 + 31616561 = 31616992

Showing the first eight; more decompositions exist.
