Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659100, here are decompositions:

3 + 8659097 = 8659100
103 + 8658997 = 8659100
139 + 8658961 = 8659100
157 + 8658943 = 8659100
181 + 8658919 = 8659100
223 + 8658877 = 8659100
271 + 8658829 = 8659100
421 + 8658679 = 8659100

Showing the first eight; more decompositions exist.
