Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989284, here are decompositions:

5 + 989279 = 989284
53 + 989231 = 989284
113 + 989171 = 989284
347 + 988937 = 989284
383 + 988901 = 989284
521 + 988763 = 989284
557 + 988727 = 989284
641 + 988643 = 989284

Showing the first eight; more decompositions exist.
