Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548048, here are decompositions:

17 + 31548031 = 31548048
19 + 31548029 = 31548048
31 + 31548017 = 31548048
41 + 31548007 = 31548048
67 + 31547981 = 31548048
89 + 31547959 = 31548048
127 + 31547921 = 31548048
131 + 31547917 = 31548048

Showing the first eight; more decompositions exist.
