Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464224, here are decompositions:

31 + 31464193 = 31464224
37 + 31464187 = 31464224
157 + 31464067 = 31464224
163 + 31464061 = 31464224
193 + 31464031 = 31464224
223 + 31464001 = 31464224
283 + 31463941 = 31464224
313 + 31463911 = 31464224

Showing the first eight; more decompositions exist.
