Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655258, here are decompositions:

41 + 8655217 = 8655258
47 + 8655211 = 8655258
61 + 8655197 = 8655258
109 + 8655149 = 8655258
211 + 8655047 = 8655258
229 + 8655029 = 8655258
251 + 8655007 = 8655258
277 + 8654981 = 8655258

Showing the first eight; more decompositions exist.
