Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504224, here are decompositions:

5 + 31504219 = 31504224
23 + 31504201 = 31504224
41 + 31504183 = 31504224
97 + 31504127 = 31504224
127 + 31504097 = 31504224
137 + 31504087 = 31504224
173 + 31504051 = 31504224
211 + 31504013 = 31504224

Showing the first eight; more decompositions exist.
