Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989630, here are decompositions:

7 + 989623 = 989630
73 + 989557 = 989630
97 + 989533 = 989630
151 + 989479 = 989630
163 + 989467 = 989630
211 + 989419 = 989630
277 + 989353 = 989630
283 + 989347 = 989630

Showing the first eight; more decompositions exist.
