Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616006, here are decompositions:

7 + 31615999 = 31616006
13 + 31615993 = 31616006
157 + 31615849 = 31616006
199 + 31615807 = 31616006
223 + 31615783 = 31616006
277 + 31615729 = 31616006
337 + 31615669 = 31616006
397 + 31615609 = 31616006

Showing the first eight; more decompositions exist.
