Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601408, here are decompositions:

7 + 8601401 = 8601408
17 + 8601391 = 8601408
19 + 8601389 = 8601408
47 + 8601361 = 8601408
131 + 8601277 = 8601408
199 + 8601209 = 8601408
239 + 8601169 = 8601408
251 + 8601157 = 8601408

Showing the first eight; more decompositions exist.
