Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168126, here are decompositions:

17 + 168109 = 168126
37 + 168089 = 168126
43 + 168083 = 168126
59 + 168067 = 168126
83 + 168043 = 168126
89 + 168037 = 168126
97 + 168029 = 168126
103 + 168023 = 168126

Showing the first eight; more decompositions exist.
