Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601564, here are decompositions:

7 + 8601557 = 8601564
53 + 8601511 = 8601564
61 + 8601503 = 8601564
73 + 8601491 = 8601564
107 + 8601457 = 8601564
163 + 8601401 = 8601564
173 + 8601391 = 8601564
233 + 8601331 = 8601564

Showing the first eight; more decompositions exist.
