Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548046, here are decompositions:

17 + 31548029 = 31548046
29 + 31548017 = 31548046
53 + 31547993 = 31548046
113 + 31547933 = 31548046
197 + 31547849 = 31548046
263 + 31547783 = 31548046
353 + 31547693 = 31548046
557 + 31547489 = 31548046

Showing the first eight; more decompositions exist.
