Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693988, here are decompositions:

5 + 8693983 = 8693988
19 + 8693969 = 8693988
29 + 8693959 = 8693988
31 + 8693957 = 8693988
41 + 8693947 = 8693988
47 + 8693941 = 8693988
71 + 8693917 = 8693988
97 + 8693891 = 8693988

Showing the first eight; more decompositions exist.
