Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989180, here are decompositions:

7 + 989173 = 989180
61 + 989119 = 989180
109 + 989071 = 989180
151 + 989029 = 989180
229 + 988951 = 989180
271 + 988909 = 989180
331 + 988849 = 989180
397 + 988783 = 989180

Showing the first eight; more decompositions exist.
