Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663998, here are decompositions:

11 + 8663987 = 8663998
29 + 8663969 = 8663998
137 + 8663861 = 8663998
179 + 8663819 = 8663998
191 + 8663807 = 8663998
257 + 8663741 = 8663998
311 + 8663687 = 8663998
389 + 8663609 = 8663998

Showing the first eight; more decompositions exist.
