Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616260, here are decompositions:

3 + 31616257 = 31616260
29 + 31616231 = 31616260
41 + 31616219 = 31616260
131 + 31616129 = 31616260
191 + 31616069 = 31616260
227 + 31616033 = 31616260
239 + 31616021 = 31616260
251 + 31616009 = 31616260

Showing the first eight; more decompositions exist.
