Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538198, here are decompositions:

41 + 538157 = 538198
47 + 538151 = 538198
71 + 538127 = 538198
149 + 538049 = 538198
179 + 538019 = 538198
197 + 538001 = 538198
257 + 537941 = 538198
449 + 537749 = 538198

Showing the first eight; more decompositions exist.
