Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534248, here are decompositions:

7 + 31534241 = 31534248
17 + 31534231 = 31534248
61 + 31534187 = 31534248
79 + 31534169 = 31534248
107 + 31534141 = 31534248
127 + 31534121 = 31534248
131 + 31534117 = 31534248
181 + 31534067 = 31534248

Showing the first eight; more decompositions exist.
