Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655238, here are decompositions:

41 + 8655197 = 8655238
71 + 8655167 = 8655238
89 + 8655149 = 8655238
167 + 8655071 = 8655238
191 + 8655047 = 8655238
197 + 8655041 = 8655238
227 + 8655011 = 8655238
257 + 8654981 = 8655238

Showing the first eight; more decompositions exist.
