Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616316, here are decompositions:

19 + 31616297 = 31616316
29 + 31616287 = 31616316
59 + 31616257 = 31616316
97 + 31616219 = 31616316
167 + 31616149 = 31616316
257 + 31616059 = 31616316
269 + 31616047 = 31616316
283 + 31616033 = 31616316

Showing the first eight; more decompositions exist.
