Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525168, here are decompositions:

5 + 525163 = 525168
11 + 525157 = 525168
31 + 525137 = 525168
41 + 525127 = 525168
67 + 525101 = 525168
139 + 525029 = 525168
151 + 525017 = 525168
167 + 525001 = 525168

Showing the first eight; more decompositions exist.
