Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476254, here are decompositions:

3 + 31476251 = 31476254
67 + 31476187 = 31476254
97 + 31476157 = 31476254
157 + 31476097 = 31476254
181 + 31476073 = 31476254
223 + 31476031 = 31476254
241 + 31476013 = 31476254
457 + 31475797 = 31476254

Showing the first eight; more decompositions exist.
