Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711984, here are decompositions:

13 + 8711971 = 8711984
31 + 8711953 = 8711984
97 + 8711887 = 8711984
163 + 8711821 = 8711984
241 + 8711743 = 8711984
277 + 8711707 = 8711984
331 + 8711653 = 8711984
367 + 8711617 = 8711984

Showing the first eight; more decompositions exist.
