Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655378, here are decompositions:

7 + 8655371 = 8655378
29 + 8655349 = 8655378
47 + 8655331 = 8655378
71 + 8655307 = 8655378
167 + 8655211 = 8655378
181 + 8655197 = 8655378
211 + 8655167 = 8655378
229 + 8655149 = 8655378

Showing the first eight; more decompositions exist.
