Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534224, here are decompositions:

37 + 31534187 = 31534224
41 + 31534183 = 31534224
83 + 31534141 = 31534224
103 + 31534121 = 31534224
107 + 31534117 = 31534224
151 + 31534073 = 31534224
157 + 31534067 = 31534224
167 + 31534057 = 31534224

Showing the first eight; more decompositions exist.
