Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659158, here are decompositions:

5 + 8659153 = 8659158
37 + 8659121 = 8659158
59 + 8659099 = 8659158
61 + 8659097 = 8659158
97 + 8659061 = 8659158
107 + 8659051 = 8659158
139 + 8659019 = 8659158
149 + 8659009 = 8659158

Showing the first eight; more decompositions exist.
