Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989658, here are decompositions:

11 + 989647 = 989658
17 + 989641 = 989658
29 + 989629 = 989658
79 + 989579 = 989658
97 + 989561 = 989658
101 + 989557 = 989658
151 + 989507 = 989658
179 + 989479 = 989658

Showing the first eight; more decompositions exist.
