Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616530, here are decompositions:

107 + 31616423 = 31616530
137 + 31616393 = 31616530
149 + 31616381 = 31616530
167 + 31616363 = 31616530
191 + 31616339 = 31616530
233 + 31616297 = 31616530
269 + 31616261 = 31616530
311 + 31616219 = 31616530

Showing the first eight; more decompositions exist.
