Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989130, here are decompositions:

7 + 989123 = 989130
11 + 989119 = 989130
31 + 989099 = 989130
59 + 989071 = 989130
71 + 989059 = 989130
101 + 989029 = 989130
151 + 988979 = 989130
167 + 988963 = 989130

Showing the first eight; more decompositions exist.
