Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538358, here are decompositions:

61 + 538297 = 538358
109 + 538249 = 538358
157 + 538201 = 538358
199 + 538159 = 538358
211 + 538147 = 538358
241 + 538117 = 538358
307 + 538051 = 538358
367 + 537991 = 538358

Showing the first eight; more decompositions exist.
