Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616898, here are decompositions:

7 + 31616891 = 31616898
11 + 31616887 = 31616898
41 + 31616857 = 31616898
59 + 31616839 = 31616898
149 + 31616749 = 31616898
151 + 31616747 = 31616898
191 + 31616707 = 31616898
211 + 31616687 = 31616898

Showing the first eight; more decompositions exist.
