Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627224, here are decompositions:

7 + 31627217 = 31627224
23 + 31627201 = 31627224
73 + 31627151 = 31627224
103 + 31627121 = 31627224
151 + 31627073 = 31627224
173 + 31627051 = 31627224
191 + 31627033 = 31627224
197 + 31627027 = 31627224

Showing the first eight; more decompositions exist.
