Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659288, here are decompositions:

107 + 8659181 = 8659288
167 + 8659121 = 8659288
191 + 8659097 = 8659288
227 + 8659061 = 8659288
251 + 8659037 = 8659288
269 + 8659019 = 8659288
311 + 8658977 = 8659288
347 + 8658941 = 8659288

Showing the first eight; more decompositions exist.
