Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655790, here are decompositions:

29 + 8655761 = 8655790
41 + 8655749 = 8655790
71 + 8655719 = 8655790
83 + 8655707 = 8655790
89 + 8655701 = 8655790
113 + 8655677 = 8655790
137 + 8655653 = 8655790
149 + 8655641 = 8655790

Showing the first eight; more decompositions exist.
