Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616060, here are decompositions:

13 + 31616047 = 31616060
19 + 31616041 = 31616060
37 + 31616023 = 31616060
43 + 31616017 = 31616060
61 + 31615999 = 31616060
67 + 31615993 = 31616060
109 + 31615951 = 31616060
139 + 31615921 = 31616060

Showing the first eight; more decompositions exist.
