Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689840, here are decompositions:

17 + 8689823 = 8689840
23 + 8689817 = 8689840
41 + 8689799 = 8689840
113 + 8689727 = 8689840
167 + 8689673 = 8689840
179 + 8689661 = 8689840
191 + 8689649 = 8689840
197 + 8689643 = 8689840

Showing the first eight; more decompositions exist.
