Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989568, here are decompositions:

7 + 989561 = 989568
11 + 989557 = 989568
61 + 989507 = 989568
89 + 989479 = 989568
101 + 989467 = 989568
127 + 989441 = 989568
149 + 989419 = 989568
157 + 989411 = 989568

Showing the first eight; more decompositions exist.
