Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689700, here are decompositions:

13 + 8689687 = 8689700
43 + 8689657 = 8689700
73 + 8689627 = 8689700
109 + 8689591 = 8689700
127 + 8689573 = 8689700
157 + 8689543 = 8689700
163 + 8689537 = 8689700
211 + 8689489 = 8689700

Showing the first eight; more decompositions exist.
