Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648458, here are decompositions:

11 + 8648447 = 8648458
89 + 8648369 = 8648458
191 + 8648267 = 8648458
347 + 8648111 = 8648458
359 + 8648099 = 8648458
461 + 8647997 = 8648458
479 + 8647979 = 8648458
491 + 8647967 = 8648458

Showing the first eight; more decompositions exist.
