Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616532, here are decompositions:

11 + 31616521 = 31616532
23 + 31616509 = 31616532
53 + 31616479 = 31616532
109 + 31616423 = 31616532
113 + 31616419 = 31616532
131 + 31616401 = 31616532
139 + 31616393 = 31616532
151 + 31616381 = 31616532

Showing the first eight; more decompositions exist.
