Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548006, here are decompositions:

13 + 31547993 = 31548006
47 + 31547959 = 31548006
53 + 31547953 = 31548006
73 + 31547933 = 31548006
89 + 31547917 = 31548006
157 + 31547849 = 31548006
167 + 31547839 = 31548006
173 + 31547833 = 31548006

Showing the first eight; more decompositions exist.
