Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989646, here are decompositions:

5 + 989641 = 989646
17 + 989629 = 989646
23 + 989623 = 989646
67 + 989579 = 989646
89 + 989557 = 989646
113 + 989533 = 989646
139 + 989507 = 989646
167 + 989479 = 989646

Showing the first eight; more decompositions exist.
