Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655198, here are decompositions:

31 + 8655167 = 8655198
127 + 8655071 = 8655198
151 + 8655047 = 8655198
157 + 8655041 = 8655198
191 + 8655007 = 8655198
239 + 8654959 = 8655198
257 + 8654941 = 8655198
281 + 8654917 = 8655198

Showing the first eight; more decompositions exist.
