Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8118, here are decompositions:

7 + 8111 = 8118
17 + 8101 = 8118
29 + 8089 = 8118
31 + 8087 = 8118
37 + 8081 = 8118
59 + 8059 = 8118
79 + 8039 = 8118
101 + 8017 = 8118

Showing the first eight; more decompositions exist.
