Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616030, here are decompositions:

7 + 31616023 = 31616030
13 + 31616017 = 31616030
31 + 31615999 = 31616030
37 + 31615993 = 31616030
79 + 31615951 = 31616030
109 + 31615921 = 31616030
139 + 31615891 = 31616030
181 + 31615849 = 31616030

Showing the first eight; more decompositions exist.
