Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548012, here are decompositions:

5 + 31548007 = 31548012
19 + 31547993 = 31548012
31 + 31547981 = 31548012
53 + 31547959 = 31548012
59 + 31547953 = 31548012
79 + 31547933 = 31548012
151 + 31547861 = 31548012
163 + 31547849 = 31548012

Showing the first eight; more decompositions exist.
