Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989748, here are decompositions:

5 + 989743 = 989748
29 + 989719 = 989748
61 + 989687 = 989748
101 + 989647 = 989748
107 + 989641 = 989748
167 + 989581 = 989748
191 + 989557 = 989748
241 + 989507 = 989748

Showing the first eight; more decompositions exist.
