Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616054, here are decompositions:

7 + 31616047 = 31616054
13 + 31616041 = 31616054
31 + 31616023 = 31616054
37 + 31616017 = 31616054
61 + 31615993 = 31616054
103 + 31615951 = 31616054
163 + 31615891 = 31616054
271 + 31615783 = 31616054

Showing the first eight; more decompositions exist.
