Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604820, here are decompositions:

11 + 8604809 = 8604820
23 + 8604797 = 8604820
41 + 8604779 = 8604820
53 + 8604767 = 8604820
71 + 8604749 = 8604820
113 + 8604707 = 8604820
131 + 8604689 = 8604820
173 + 8604647 = 8604820

Showing the first eight; more decompositions exist.
