Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718884, here are decompositions:

3 + 8718881 = 8718884
7 + 8718877 = 8718884
61 + 8718823 = 8718884
73 + 8718811 = 8718884
127 + 8718757 = 8718884
151 + 8718733 = 8718884
157 + 8718727 = 8718884
211 + 8718673 = 8718884

Showing the first eight; more decompositions exist.
