Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989724, here are decompositions:

5 + 989719 = 989724
37 + 989687 = 989724
53 + 989671 = 989724
61 + 989663 = 989724
83 + 989641 = 989724
101 + 989623 = 989724
163 + 989561 = 989724
167 + 989557 = 989724

Showing the first eight; more decompositions exist.
