Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661998, here are decompositions:

97 + 8661901 = 8661998
109 + 8661889 = 8661998
127 + 8661871 = 8661998
157 + 8661841 = 8661998
199 + 8661799 = 8661998
229 + 8661769 = 8661998
271 + 8661727 = 8661998
421 + 8661577 = 8661998

Showing the first eight; more decompositions exist.
