Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527224, here are decompositions:

13 + 31527211 = 31527224
31 + 31527193 = 31527224
67 + 31527157 = 31527224
73 + 31527151 = 31527224
271 + 31526953 = 31527224
283 + 31526941 = 31527224
331 + 31526893 = 31527224
433 + 31526791 = 31527224

Showing the first eight; more decompositions exist.
