Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989220, here are decompositions:

47 + 989173 = 989220
97 + 989123 = 989220
101 + 989119 = 989220
139 + 989081 = 989220
149 + 989071 = 989220
191 + 989029 = 989220
241 + 988979 = 989220
257 + 988963 = 989220

Showing the first eight; more decompositions exist.
