Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615026, here are decompositions:

13 + 31615013 = 31615026
19 + 31615007 = 31615026
73 + 31614953 = 31615026
83 + 31614943 = 31615026
97 + 31614929 = 31615026
127 + 31614899 = 31615026
137 + 31614889 = 31615026
167 + 31614859 = 31615026

Showing the first eight; more decompositions exist.
