Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689906, here are decompositions:

53 + 8689853 = 8689906
83 + 8689823 = 8689906
89 + 8689817 = 8689906
107 + 8689799 = 8689906
179 + 8689727 = 8689906
233 + 8689673 = 8689906
257 + 8689649 = 8689906
263 + 8689643 = 8689906

Showing the first eight; more decompositions exist.
