Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689436, here are decompositions:

3 + 8689433 = 8689436
37 + 8689399 = 8689436
127 + 8689309 = 8689436
157 + 8689279 = 8689436
163 + 8689273 = 8689436
193 + 8689243 = 8689436
307 + 8689129 = 8689436
367 + 8689069 = 8689436

Showing the first eight; more decompositions exist.
