Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616622, here are decompositions:

19 + 31616603 = 31616622
43 + 31616579 = 31616622
53 + 31616569 = 31616622
61 + 31616561 = 31616622
83 + 31616539 = 31616622
101 + 31616521 = 31616622
113 + 31616509 = 31616622
199 + 31616423 = 31616622

Showing the first eight; more decompositions exist.
