Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609404, here are decompositions:

71 + 8609333 = 8609404
107 + 8609297 = 8609404
131 + 8609273 = 8609404
197 + 8609207 = 8609404
311 + 8609093 = 8609404
317 + 8609087 = 8609404
431 + 8608973 = 8609404
491 + 8608913 = 8609404

Showing the first eight; more decompositions exist.
