Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601428, here are decompositions:

7 + 8601421 = 8601428
37 + 8601391 = 8601428
67 + 8601361 = 8601428
97 + 8601331 = 8601428
139 + 8601289 = 8601428
151 + 8601277 = 8601428
271 + 8601157 = 8601428
307 + 8601121 = 8601428

Showing the first eight; more decompositions exist.
