Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8112, here are decompositions:

11 + 8101 = 8112
19 + 8093 = 8112
23 + 8089 = 8112
31 + 8081 = 8112
43 + 8069 = 8112
53 + 8059 = 8112
59 + 8053 = 8112
73 + 8039 = 8112

Showing the first eight; more decompositions exist.
