Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616852, here are decompositions:

13 + 31616839 = 31616852
79 + 31616773 = 31616852
103 + 31616749 = 31616852
181 + 31616671 = 31616852
229 + 31616623 = 31616852
283 + 31616569 = 31616852
313 + 31616539 = 31616852
331 + 31616521 = 31616852

Showing the first eight; more decompositions exist.
