Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655498, here are decompositions:

41 + 8655457 = 8655498
97 + 8655401 = 8655498
127 + 8655371 = 8655498
149 + 8655349 = 8655498
167 + 8655331 = 8655498
191 + 8655307 = 8655498
211 + 8655287 = 8655498
239 + 8655259 = 8655498

Showing the first eight; more decompositions exist.
