Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601572, here are decompositions:

3 + 8601569 = 8601572
61 + 8601511 = 8601572
73 + 8601499 = 8601572
151 + 8601421 = 8601572
181 + 8601391 = 8601572
211 + 8601361 = 8601572
229 + 8601343 = 8601572
241 + 8601331 = 8601572

Showing the first eight; more decompositions exist.
