Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689492, here are decompositions:

3 + 8689489 = 8689492
11 + 8689481 = 8689492
29 + 8689463 = 8689492
41 + 8689451 = 8689492
59 + 8689433 = 8689492
173 + 8689319 = 8689492
191 + 8689301 = 8689492
233 + 8689259 = 8689492

Showing the first eight; more decompositions exist.
