Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989450, here are decompositions:

31 + 989419 = 989450
73 + 989377 = 989450
97 + 989353 = 989450
103 + 989347 = 989450
109 + 989341 = 989450
127 + 989323 = 989450
157 + 989293 = 989450
199 + 989251 = 989450

Showing the first eight; more decompositions exist.
