Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616224, here are decompositions:

5 + 31616219 = 31616224
41 + 31616183 = 31616224
191 + 31616033 = 31616224
251 + 31615973 = 31616224
461 + 31615763 = 31616224
467 + 31615757 = 31616224
641 + 31615583 = 31616224
821 + 31615403 = 31616224

Showing the first eight; more decompositions exist.
