Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601580, here are decompositions:

11 + 8601569 = 8601580
23 + 8601557 = 8601580
89 + 8601491 = 8601580
131 + 8601449 = 8601580
137 + 8601443 = 8601580
179 + 8601401 = 8601580
191 + 8601389 = 8601580
347 + 8601233 = 8601580

Showing the first eight; more decompositions exist.
