Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616414, here are decompositions:

3 + 31616411 = 31616414
13 + 31616401 = 31616414
127 + 31616287 = 31616414
157 + 31616257 = 31616414
163 + 31616251 = 31616414
241 + 31616173 = 31616414
367 + 31616047 = 31616414
373 + 31616041 = 31616414

Showing the first eight; more decompositions exist.
