Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655772, here are decompositions:

3 + 8655769 = 8655772
11 + 8655761 = 8655772
23 + 8655749 = 8655772
53 + 8655719 = 8655772
71 + 8655701 = 8655772
101 + 8655671 = 8655772
131 + 8655641 = 8655772
149 + 8655623 = 8655772

Showing the first eight; more decompositions exist.
