Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689998, here are decompositions:

11 + 8689987 = 8689998
17 + 8689981 = 8689998
19 + 8689979 = 8689998
29 + 8689969 = 8689998
41 + 8689957 = 8689998
157 + 8689841 = 8689998
181 + 8689817 = 8689998
199 + 8689799 = 8689998

Showing the first eight; more decompositions exist.
