Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609400, here are decompositions:

29 + 8609371 = 8609400
47 + 8609353 = 8609400
53 + 8609347 = 8609400
67 + 8609333 = 8609400
103 + 8609297 = 8609400
113 + 8609287 = 8609400
127 + 8609273 = 8609400
131 + 8609269 = 8609400

Showing the first eight; more decompositions exist.
