Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454224, here are decompositions:

3 + 31454221 = 31454224
5 + 31454219 = 31454224
23 + 31454201 = 31454224
101 + 31454123 = 31454224
107 + 31454117 = 31454224
227 + 31453997 = 31454224
233 + 31453991 = 31454224
281 + 31453943 = 31454224

Showing the first eight; more decompositions exist.
