Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576224, here are decompositions:

5 + 31576219 = 31576224
13 + 31576211 = 31576224
23 + 31576201 = 31576224
37 + 31576187 = 31576224
61 + 31576163 = 31576224
103 + 31576121 = 31576224
107 + 31576117 = 31576224
137 + 31576087 = 31576224

Showing the first eight; more decompositions exist.
