Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989666, here are decompositions:

3 + 989663 = 989666
19 + 989647 = 989666
37 + 989629 = 989666
43 + 989623 = 989666
109 + 989557 = 989666
199 + 989467 = 989666
313 + 989353 = 989666
373 + 989293 = 989666

Showing the first eight; more decompositions exist.
