Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7894, here are decompositions:

11 + 7883 = 7894
17 + 7877 = 7894
41 + 7853 = 7894
53 + 7841 = 7894
71 + 7823 = 7894
101 + 7793 = 7894
137 + 7757 = 7894
167 + 7727 = 7894

Showing the first eight; more decompositions exist.
