Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616844, here are decompositions:

5 + 31616839 = 31616844
71 + 31616773 = 31616844
97 + 31616747 = 31616844
137 + 31616707 = 31616844
151 + 31616693 = 31616844
157 + 31616687 = 31616844
167 + 31616677 = 31616844
173 + 31616671 = 31616844

Showing the first eight; more decompositions exist.
