Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532416, here are decompositions:

137 + 31532279 = 31532416
197 + 31532219 = 31532416
353 + 31532063 = 31532416
449 + 31531967 = 31532416
599 + 31531817 = 31532416
1013 + 31531403 = 31532416
1277 + 31531139 = 31532416
1439 + 31530977 = 31532416

Showing the first eight; more decompositions exist.
