Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938450, here are decompositions:

3 + 938447 = 938450
13 + 938437 = 938450
103 + 938347 = 938450
109 + 938341 = 938450
127 + 938323 = 938450
157 + 938293 = 938450
193 + 938257 = 938450
199 + 938251 = 938450

Showing the first eight; more decompositions exist.
