Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655884, here are decompositions:

7 + 8655877 = 8655884
43 + 8655841 = 8655884
151 + 8655733 = 8655884
163 + 8655721 = 8655884
463 + 8655421 = 8655884
541 + 8655343 = 8655884
571 + 8655313 = 8655884
577 + 8655307 = 8655884

Showing the first eight; more decompositions exist.
