Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8142, here are decompositions:

19 + 8123 = 8142
31 + 8111 = 8142
41 + 8101 = 8142
53 + 8089 = 8142
61 + 8081 = 8142
73 + 8069 = 8142
83 + 8059 = 8142
89 + 8053 = 8142

Showing the first eight; more decompositions exist.
