Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648356, here are decompositions:

23 + 8648333 = 8648356
89 + 8648267 = 8648356
257 + 8648099 = 8648356
263 + 8648093 = 8648356
359 + 8647997 = 8648356
389 + 8647967 = 8648356
419 + 8647937 = 8648356
443 + 8647913 = 8648356

Showing the first eight; more decompositions exist.
