Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601280, here are decompositions:

3 + 8601277 = 8601280
47 + 8601233 = 8601280
71 + 8601209 = 8601280
89 + 8601191 = 8601280
137 + 8601143 = 8601280
167 + 8601113 = 8601280
173 + 8601107 = 8601280
179 + 8601101 = 8601280

Showing the first eight; more decompositions exist.
