Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655328, here are decompositions:

41 + 8655287 = 8655328
131 + 8655197 = 8655328
179 + 8655149 = 8655328
257 + 8655071 = 8655328
281 + 8655047 = 8655328
317 + 8655011 = 8655328
347 + 8654981 = 8655328
431 + 8654897 = 8655328

Showing the first eight; more decompositions exist.
