Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669998, here are decompositions:

5 + 8669993 = 8669998
17 + 8669981 = 8669998
59 + 8669939 = 8669998
101 + 8669897 = 8669998
137 + 8669861 = 8669998
167 + 8669831 = 8669998
347 + 8669651 = 8669998
509 + 8669489 = 8669998

Showing the first eight; more decompositions exist.
