Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537224, here are decompositions:

23 + 31537201 = 31537224
71 + 31537153 = 31537224
73 + 31537151 = 31537224
97 + 31537127 = 31537224
127 + 31537097 = 31537224
137 + 31537087 = 31537224
181 + 31537043 = 31537224
197 + 31537027 = 31537224

Showing the first eight; more decompositions exist.
