Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616002, here are decompositions:

3 + 31615999 = 31616002
23 + 31615979 = 31616002
29 + 31615973 = 31616002
83 + 31615919 = 31616002
239 + 31615763 = 31616002
419 + 31615583 = 31616002
563 + 31615439 = 31616002
599 + 31615403 = 31616002

Showing the first eight; more decompositions exist.
