Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989216, here are decompositions:

43 + 989173 = 989216
97 + 989119 = 989216
157 + 989059 = 989216
307 + 988909 = 989216
367 + 988849 = 989216
379 + 988837 = 989216
433 + 988783 = 989216
457 + 988759 = 989216

Showing the first eight; more decompositions exist.
