Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699988, here are decompositions:

7 + 8699981 = 8699988
19 + 8699969 = 8699988
29 + 8699959 = 8699988
41 + 8699947 = 8699988
71 + 8699917 = 8699988
109 + 8699879 = 8699988
131 + 8699857 = 8699988
137 + 8699851 = 8699988

Showing the first eight; more decompositions exist.
