Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659180, here are decompositions:

59 + 8659121 = 8659180
83 + 8659097 = 8659180
113 + 8659067 = 8659180
137 + 8659043 = 8659180
191 + 8658989 = 8659180
197 + 8658983 = 8659180
239 + 8658941 = 8659180
269 + 8658911 = 8659180

Showing the first eight; more decompositions exist.
