Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989744, here are decompositions:

73 + 989671 = 989744
97 + 989647 = 989744
103 + 989641 = 989744
163 + 989581 = 989744
211 + 989533 = 989744
277 + 989467 = 989744
367 + 989377 = 989744
397 + 989347 = 989744

Showing the first eight; more decompositions exist.
