Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605042, here are decompositions:

23 + 8605019 = 8605042
41 + 8605001 = 8605042
59 + 8604983 = 8605042
179 + 8604863 = 8605042
233 + 8604809 = 8605042
263 + 8604779 = 8605042
293 + 8604749 = 8605042
353 + 8604689 = 8605042

Showing the first eight; more decompositions exist.
