Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8190, here are decompositions:

11 + 8179 = 8190
19 + 8171 = 8190
23 + 8167 = 8190
29 + 8161 = 8190
43 + 8147 = 8190
67 + 8123 = 8190
73 + 8117 = 8190
79 + 8111 = 8190

Showing the first eight; more decompositions exist.
