Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601228, here are decompositions:

19 + 8601209 = 8601228
37 + 8601191 = 8601228
59 + 8601169 = 8601228
71 + 8601157 = 8601228
107 + 8601121 = 8601228
127 + 8601101 = 8601228
131 + 8601097 = 8601228
151 + 8601077 = 8601228

Showing the first eight; more decompositions exist.
