Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616552, here are decompositions:

13 + 31616539 = 31616552
31 + 31616521 = 31616552
43 + 31616509 = 31616552
73 + 31616479 = 31616552
151 + 31616401 = 31616552
193 + 31616359 = 31616552
271 + 31616281 = 31616552
379 + 31616173 = 31616552

Showing the first eight; more decompositions exist.
