Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648278, here are decompositions:

11 + 8648267 = 8648278
167 + 8648111 = 8648278
179 + 8648099 = 8648278
281 + 8647997 = 8648278
311 + 8647967 = 8648278
389 + 8647889 = 8648278
461 + 8647817 = 8648278
809 + 8647469 = 8648278

Showing the first eight; more decompositions exist.
