Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534278, here are decompositions:

7 + 31534271 = 31534278
31 + 31534247 = 31534278
37 + 31534241 = 31534278
47 + 31534231 = 31534278
79 + 31534199 = 31534278
109 + 31534169 = 31534278
137 + 31534141 = 31534278
157 + 31534121 = 31534278

Showing the first eight; more decompositions exist.
