Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476894, here are decompositions:

13 + 31476881 = 31476894
23 + 31476871 = 31476894
41 + 31476853 = 31476894
47 + 31476847 = 31476894
73 + 31476821 = 31476894
151 + 31476743 = 31476894
167 + 31476727 = 31476894
191 + 31476703 = 31476894

Showing the first eight; more decompositions exist.
