Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689372, here are decompositions:

23 + 8689349 = 8689372
53 + 8689319 = 8689372
71 + 8689301 = 8689372
89 + 8689283 = 8689372
113 + 8689259 = 8689372
149 + 8689223 = 8689372
191 + 8689181 = 8689372
239 + 8689133 = 8689372

Showing the first eight; more decompositions exist.
