Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989286, here are decompositions:

7 + 989279 = 989286
37 + 989249 = 989286
47 + 989239 = 989286
113 + 989173 = 989286
163 + 989123 = 989286
167 + 989119 = 989286
227 + 989059 = 989286
257 + 989029 = 989286

Showing the first eight; more decompositions exist.
