Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616548, here are decompositions:

137 + 31616411 = 31616548
167 + 31616381 = 31616548
179 + 31616369 = 31616548
251 + 31616297 = 31616548
317 + 31616231 = 31616548
419 + 31616129 = 31616548
479 + 31616069 = 31616548
569 + 31615979 = 31616548

Showing the first eight; more decompositions exist.
