Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546284, here are decompositions:

5 + 31546279 = 31546284
17 + 31546267 = 31546284
53 + 31546231 = 31546284
67 + 31546217 = 31546284
97 + 31546187 = 31546284
103 + 31546181 = 31546284
131 + 31546153 = 31546284
173 + 31546111 = 31546284

Showing the first eight; more decompositions exist.
