Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989768, here are decompositions:

7 + 989761 = 989768
19 + 989749 = 989768
97 + 989671 = 989768
127 + 989641 = 989768
139 + 989629 = 989768
211 + 989557 = 989768
349 + 989419 = 989768
421 + 989347 = 989768

Showing the first eight; more decompositions exist.
