Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532188, here are decompositions:

5 + 532183 = 532188
29 + 532159 = 532188
47 + 532141 = 532188
89 + 532099 = 532188
127 + 532061 = 532188
179 + 532009 = 532188
191 + 531997 = 532188
199 + 531989 = 532188

Showing the first eight; more decompositions exist.
