Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598224, here are decompositions:

11 + 31598213 = 31598224
23 + 31598201 = 31598224
83 + 31598141 = 31598224
167 + 31598057 = 31598224
191 + 31598033 = 31598224
197 + 31598027 = 31598224
227 + 31597997 = 31598224
263 + 31597961 = 31598224

Showing the first eight; more decompositions exist.
