Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532216, here are decompositions:

7 + 31532209 = 31532216
13 + 31532203 = 31532216
103 + 31532113 = 31532216
127 + 31532089 = 31532216
307 + 31531909 = 31532216
577 + 31531639 = 31532216
733 + 31531483 = 31532216
967 + 31531249 = 31532216

Showing the first eight; more decompositions exist.
