Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616302, here are decompositions:

5 + 31616297 = 31616302
41 + 31616261 = 31616302
71 + 31616231 = 31616302
83 + 31616219 = 31616302
173 + 31616129 = 31616302
233 + 31616069 = 31616302
269 + 31616033 = 31616302
281 + 31616021 = 31616302

Showing the first eight; more decompositions exist.
