Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616684, here are decompositions:

7 + 31616677 = 31616684
13 + 31616671 = 31616684
37 + 31616647 = 31616684
61 + 31616623 = 31616684
163 + 31616521 = 31616684
283 + 31616401 = 31616684
397 + 31616287 = 31616684
433 + 31616251 = 31616684

Showing the first eight; more decompositions exist.
