Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605040, here are decompositions:

79 + 8604961 = 8605040
97 + 8604943 = 8605040
127 + 8604913 = 8605040
229 + 8604811 = 8605040
271 + 8604769 = 8605040
307 + 8604733 = 8605040
373 + 8604667 = 8605040
397 + 8604643 = 8605040

Showing the first eight; more decompositions exist.
