Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717984, here are decompositions:

3 + 8717981 = 8717984
103 + 8717881 = 8717984
127 + 8717857 = 8717984
181 + 8717803 = 8717984
193 + 8717791 = 8717984
211 + 8717773 = 8717984
241 + 8717743 = 8717984
307 + 8717677 = 8717984

Showing the first eight; more decompositions exist.
