Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182190, here are decompositions:

11 + 182179 = 182190
13 + 182177 = 182190
23 + 182167 = 182190
31 + 182159 = 182190
59 + 182131 = 182190
61 + 182129 = 182190
67 + 182123 = 182190
79 + 182111 = 182190

Showing the first eight; more decompositions exist.
