Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8154, here are decompositions:

7 + 8147 = 8154
31 + 8123 = 8154
37 + 8117 = 8154
43 + 8111 = 8154
53 + 8101 = 8154
61 + 8093 = 8154
67 + 8087 = 8154
73 + 8081 = 8154

Showing the first eight; more decompositions exist.
