Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548894, here are decompositions:

23 + 31548871 = 31548894
37 + 31548857 = 31548894
71 + 31548823 = 31548894
127 + 31548767 = 31548894
131 + 31548763 = 31548894
137 + 31548757 = 31548894
151 + 31548743 = 31548894
197 + 31548697 = 31548894

Showing the first eight; more decompositions exist.
