Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659140, here are decompositions:

19 + 8659121 = 8659140
41 + 8659099 = 8659140
43 + 8659097 = 8659140
73 + 8659067 = 8659140
79 + 8659061 = 8659140
89 + 8659051 = 8659140
97 + 8659043 = 8659140
103 + 8659037 = 8659140

Showing the first eight; more decompositions exist.
