Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689446, here are decompositions:

13 + 8689433 = 8689446
47 + 8689399 = 8689446
97 + 8689349 = 8689446
127 + 8689319 = 8689446
137 + 8689309 = 8689446
163 + 8689283 = 8689446
167 + 8689279 = 8689446
173 + 8689273 = 8689446

Showing the first eight; more decompositions exist.
