Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168240, here are decompositions:

13 + 168227 = 168240
29 + 168211 = 168240
43 + 168197 = 168240
47 + 168193 = 168240
89 + 168151 = 168240
97 + 168143 = 168240
113 + 168127 = 168240
131 + 168109 = 168240

Showing the first eight; more decompositions exist.
