Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617224, here are decompositions:

43 + 31617181 = 31617224
151 + 31617073 = 31617224
211 + 31617013 = 31617224
307 + 31616917 = 31617224
337 + 31616887 = 31617224
367 + 31616857 = 31617224
547 + 31616677 = 31617224
577 + 31616647 = 31617224

Showing the first eight; more decompositions exist.
