Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601372, here are decompositions:

11 + 8601361 = 8601372
29 + 8601343 = 8601372
41 + 8601331 = 8601372
79 + 8601293 = 8601372
83 + 8601289 = 8601372
139 + 8601233 = 8601372
163 + 8601209 = 8601372
181 + 8601191 = 8601372

Showing the first eight; more decompositions exist.
