Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689902, here are decompositions:

59 + 8689843 = 8689902
61 + 8689841 = 8689902
79 + 8689823 = 8689902
103 + 8689799 = 8689902
149 + 8689753 = 8689902
173 + 8689729 = 8689902
191 + 8689711 = 8689902
229 + 8689673 = 8689902

Showing the first eight; more decompositions exist.
