Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689884, here are decompositions:

31 + 8689853 = 8689884
41 + 8689843 = 8689884
43 + 8689841 = 8689884
61 + 8689823 = 8689884
67 + 8689817 = 8689884
107 + 8689777 = 8689884
131 + 8689753 = 8689884
157 + 8689727 = 8689884

Showing the first eight; more decompositions exist.
