Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616522, here are decompositions:

13 + 31616509 = 31616522
43 + 31616479 = 31616522
103 + 31616419 = 31616522
163 + 31616359 = 31616522
241 + 31616281 = 31616522
271 + 31616251 = 31616522
349 + 31616173 = 31616522
373 + 31616149 = 31616522

Showing the first eight; more decompositions exist.
