Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601156, here are decompositions:

13 + 8601143 = 8601156
43 + 8601113 = 8601156
59 + 8601097 = 8601156
73 + 8601083 = 8601156
79 + 8601077 = 8601156
127 + 8601029 = 8601156
197 + 8600959 = 8601156
199 + 8600957 = 8601156

Showing the first eight; more decompositions exist.
