Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655980, here are decompositions:

13 + 8655967 = 8655980
43 + 8655937 = 8655980
61 + 8655919 = 8655980
79 + 8655901 = 8655980
97 + 8655883 = 8655980
103 + 8655877 = 8655980
139 + 8655841 = 8655980
211 + 8655769 = 8655980

Showing the first eight; more decompositions exist.
