Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647446, here are decompositions:

29 + 8647417 = 8647446
37 + 8647409 = 8647446
53 + 8647393 = 8647446
79 + 8647367 = 8647446
97 + 8647349 = 8647446
173 + 8647273 = 8647446
193 + 8647253 = 8647446
263 + 8647183 = 8647446

Showing the first eight; more decompositions exist.
