Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716988, here are decompositions:

31 + 8716957 = 8716988
97 + 8716891 = 8716988
127 + 8716861 = 8716988
229 + 8716759 = 8716988
349 + 8716639 = 8716988
409 + 8716579 = 8716988
421 + 8716567 = 8716988
457 + 8716531 = 8716988

Showing the first eight; more decompositions exist.
