Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655288, here are decompositions:

29 + 8655259 = 8655288
71 + 8655217 = 8655288
139 + 8655149 = 8655288
241 + 8655047 = 8655288
251 + 8655037 = 8655288
277 + 8655011 = 8655288
281 + 8655007 = 8655288
307 + 8654981 = 8655288

Showing the first eight; more decompositions exist.
