Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648170, here are decompositions:

59 + 8648111 = 8648170
71 + 8648099 = 8648170
137 + 8648033 = 8648170
173 + 8647997 = 8648170
191 + 8647979 = 8648170
233 + 8647937 = 8648170
257 + 8647913 = 8648170
281 + 8647889 = 8648170

Showing the first eight; more decompositions exist.
