Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546248, here are decompositions:

17 + 31546231 = 31546248
31 + 31546217 = 31546248
61 + 31546187 = 31546248
67 + 31546181 = 31546248
89 + 31546159 = 31546248
137 + 31546111 = 31546248
179 + 31546069 = 31546248
229 + 31546019 = 31546248

Showing the first eight; more decompositions exist.
