Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532218, here are decompositions:

19 + 532199 = 532218
31 + 532187 = 532218
59 + 532159 = 532218
149 + 532069 = 532218
157 + 532061 = 532218
191 + 532027 = 532218
229 + 531989 = 532218
241 + 531977 = 532218

Showing the first eight; more decompositions exist.
