Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538168, here are decompositions:

5 + 538163 = 538168
11 + 538157 = 538168
17 + 538151 = 538168
41 + 538127 = 538168
47 + 538121 = 538168
89 + 538079 = 538168
149 + 538019 = 538168
167 + 538001 = 538168

Showing the first eight; more decompositions exist.
