Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617884, here are decompositions:

7 + 8617877 = 8617884
13 + 8617871 = 8617884
47 + 8617837 = 8617884
61 + 8617823 = 8617884
97 + 8617787 = 8617884
131 + 8617753 = 8617884
181 + 8617703 = 8617884
257 + 8617627 = 8617884

Showing the first eight; more decompositions exist.
