Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989160, here are decompositions:

37 + 989123 = 989160
41 + 989119 = 989160
61 + 989099 = 989160
79 + 989081 = 989160
89 + 989071 = 989160
101 + 989059 = 989160
131 + 989029 = 989160
149 + 989011 = 989160

Showing the first eight; more decompositions exist.
