Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708820, here are decompositions:

13 + 8708807 = 8708820
17 + 8708803 = 8708820
79 + 8708741 = 8708820
89 + 8708731 = 8708820
103 + 8708717 = 8708820
157 + 8708663 = 8708820
163 + 8708657 = 8708820
181 + 8708639 = 8708820

Showing the first eight; more decompositions exist.
