Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16242, here are decompositions:

11 + 16231 = 16242
13 + 16229 = 16242
19 + 16223 = 16242
53 + 16189 = 16242
59 + 16183 = 16242
101 + 16141 = 16242
103 + 16139 = 16242
131 + 16111 = 16242

Showing the first eight; more decompositions exist.
