Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989178, here are decompositions:

5 + 989173 = 989178
7 + 989171 = 989178
59 + 989119 = 989178
79 + 989099 = 989178
97 + 989081 = 989178
107 + 989071 = 989178
149 + 989029 = 989178
167 + 989011 = 989178

Showing the first eight; more decompositions exist.
