Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689438, here are decompositions:

5 + 8689433 = 8689438
89 + 8689349 = 8689438
137 + 8689301 = 8689438
179 + 8689259 = 8689438
257 + 8689181 = 8689438
269 + 8689169 = 8689438
647 + 8688791 = 8689438
809 + 8688629 = 8689438

Showing the first eight; more decompositions exist.
