Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548772, here are decompositions:

5 + 31548767 = 31548772
23 + 31548749 = 31548772
29 + 31548743 = 31548772
113 + 31548659 = 31548772
131 + 31548641 = 31548772
179 + 31548593 = 31548772
239 + 31548533 = 31548772
251 + 31548521 = 31548772

Showing the first eight; more decompositions exist.
