Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448224, here are decompositions:

23 + 31448201 = 31448224
53 + 31448171 = 31448224
83 + 31448141 = 31448224
113 + 31448111 = 31448224
167 + 31448057 = 31448224
191 + 31448033 = 31448224
257 + 31447967 = 31448224
263 + 31447961 = 31448224

Showing the first eight; more decompositions exist.
