Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625984, here are decompositions:

5 + 8625979 = 8625984
11 + 8625973 = 8625984
23 + 8625961 = 8625984
71 + 8625913 = 8625984
83 + 8625901 = 8625984
131 + 8625853 = 8625984
151 + 8625833 = 8625984
163 + 8625821 = 8625984

Showing the first eight; more decompositions exist.
