Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608894, here are decompositions:

7 + 31608887 = 31608894
11 + 31608883 = 31608894
41 + 31608853 = 31608894
43 + 31608851 = 31608894
71 + 31608823 = 31608894
73 + 31608821 = 31608894
101 + 31608793 = 31608894
137 + 31608757 = 31608894

Showing the first eight; more decompositions exist.
