Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689820, here are decompositions:

3 + 8689817 = 8689820
43 + 8689777 = 8689820
67 + 8689753 = 8689820
109 + 8689711 = 8689820
163 + 8689657 = 8689820
193 + 8689627 = 8689820
211 + 8689609 = 8689820
229 + 8689591 = 8689820

Showing the first eight; more decompositions exist.
