Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609440, here are decompositions:

29 + 8609411 = 8609440
107 + 8609333 = 8609440
131 + 8609309 = 8609440
167 + 8609273 = 8609440
233 + 8609207 = 8609440
311 + 8609129 = 8609440
347 + 8609093 = 8609440
353 + 8609087 = 8609440

Showing the first eight; more decompositions exist.
