Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616626, here are decompositions:

3 + 31616623 = 31616626
23 + 31616603 = 31616626
47 + 31616579 = 31616626
233 + 31616393 = 31616626
257 + 31616369 = 31616626
263 + 31616363 = 31616626
443 + 31616183 = 31616626
557 + 31616069 = 31616626

Showing the first eight; more decompositions exist.
