Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476224, here are decompositions:

37 + 31476187 = 31476224
67 + 31476157 = 31476224
127 + 31476097 = 31476224
151 + 31476073 = 31476224
193 + 31476031 = 31476224
211 + 31476013 = 31476224
271 + 31475953 = 31476224
313 + 31475911 = 31476224

Showing the first eight; more decompositions exist.
