Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609380, here are decompositions:

47 + 8609333 = 8609380
71 + 8609309 = 8609380
83 + 8609297 = 8609380
107 + 8609273 = 8609380
173 + 8609207 = 8609380
251 + 8609129 = 8609380
281 + 8609099 = 8609380
293 + 8609087 = 8609380

Showing the first eight; more decompositions exist.
