Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548082, here are decompositions:

3 + 31548079 = 31548082
53 + 31548029 = 31548082
89 + 31547993 = 31548082
101 + 31547981 = 31548082
149 + 31547933 = 31548082
233 + 31547849 = 31548082
389 + 31547693 = 31548082
491 + 31547591 = 31548082

Showing the first eight; more decompositions exist.
