Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719884, here are decompositions:

11 + 8719873 = 8719884
37 + 8719847 = 8719884
53 + 8719831 = 8719884
67 + 8719817 = 8719884
71 + 8719813 = 8719884
83 + 8719801 = 8719884
113 + 8719771 = 8719884
137 + 8719747 = 8719884

Showing the first eight; more decompositions exist.
