Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168518, here are decompositions:

19 + 168499 = 168518
37 + 168481 = 168518
61 + 168457 = 168518
67 + 168451 = 168518
109 + 168409 = 168518
127 + 168391 = 168518
241 + 168277 = 168518
271 + 168247 = 168518

Showing the first eight; more decompositions exist.
