Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655700, here are decompositions:

23 + 8655677 = 8655700
29 + 8655671 = 8655700
47 + 8655653 = 8655700
59 + 8655641 = 8655700
71 + 8655629 = 8655700
89 + 8655611 = 8655700
173 + 8655527 = 8655700
503 + 8655197 = 8655700

Showing the first eight; more decompositions exist.
