Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548472, here are decompositions:

5 + 31548467 = 31548472
29 + 31548443 = 31548472
41 + 31548431 = 31548472
71 + 31548401 = 31548472
149 + 31548323 = 31548472
173 + 31548299 = 31548472
191 + 31548281 = 31548472
443 + 31548029 = 31548472

Showing the first eight; more decompositions exist.
