Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663838, here are decompositions:

11 + 8663827 = 8663838
17 + 8663821 = 8663838
19 + 8663819 = 8663838
31 + 8663807 = 8663838
41 + 8663797 = 8663838
61 + 8663777 = 8663838
97 + 8663741 = 8663838
137 + 8663701 = 8663838

Showing the first eight; more decompositions exist.
