Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655286, here are decompositions:

23 + 8655263 = 8655286
89 + 8655197 = 8655286
113 + 8655173 = 8655286
137 + 8655149 = 8655286
239 + 8655047 = 8655286
257 + 8655029 = 8655286
389 + 8654897 = 8655286
449 + 8654837 = 8655286

Showing the first eight; more decompositions exist.
