Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747988, here are decompositions:

17 + 8747971 = 8747988
31 + 8747957 = 8747988
47 + 8747941 = 8747988
59 + 8747929 = 8747988
61 + 8747927 = 8747988
71 + 8747917 = 8747988
97 + 8747891 = 8747988
131 + 8747857 = 8747988

Showing the first eight; more decompositions exist.
