Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548072, here are decompositions:

41 + 31548031 = 31548072
43 + 31548029 = 31548072
79 + 31547993 = 31548072
113 + 31547959 = 31548072
139 + 31547933 = 31548072
151 + 31547921 = 31548072
211 + 31547861 = 31548072
223 + 31547849 = 31548072

Showing the first eight; more decompositions exist.
