Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601820, here are decompositions:

47 + 8601773 = 8601820
53 + 8601767 = 8601820
113 + 8601707 = 8601820
131 + 8601689 = 8601820
137 + 8601683 = 8601820
167 + 8601653 = 8601820
173 + 8601647 = 8601820
179 + 8601641 = 8601820

Showing the first eight; more decompositions exist.
