Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616952, here are decompositions:

19 + 31616933 = 31616952
23 + 31616929 = 31616952
61 + 31616891 = 31616952
113 + 31616839 = 31616952
179 + 31616773 = 31616952
223 + 31616729 = 31616952
281 + 31616671 = 31616952
349 + 31616603 = 31616952

Showing the first eight; more decompositions exist.
