Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689812, here are decompositions:

13 + 8689799 = 8689812
59 + 8689753 = 8689812
83 + 8689729 = 8689812
101 + 8689711 = 8689812
139 + 8689673 = 8689812
151 + 8689661 = 8689812
163 + 8689649 = 8689812
239 + 8689573 = 8689812

Showing the first eight; more decompositions exist.
