Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601558, here are decompositions:

47 + 8601511 = 8601558
59 + 8601499 = 8601558
67 + 8601491 = 8601558
101 + 8601457 = 8601558
109 + 8601449 = 8601558
137 + 8601421 = 8601558
157 + 8601401 = 8601558
167 + 8601391 = 8601558

Showing the first eight; more decompositions exist.
