Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536894, here are decompositions:

23 + 31536871 = 31536894
31 + 31536863 = 31536894
47 + 31536847 = 31536894
71 + 31536823 = 31536894
73 + 31536821 = 31536894
101 + 31536793 = 31536894
163 + 31536731 = 31536894
197 + 31536697 = 31536894

Showing the first eight; more decompositions exist.
