Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989402, here are decompositions:

61 + 989341 = 989402
79 + 989323 = 989402
109 + 989293 = 989402
151 + 989251 = 989402
163 + 989239 = 989402
229 + 989173 = 989402
283 + 989119 = 989402
331 + 989071 = 989402

Showing the first eight; more decompositions exist.
