Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648394, here are decompositions:

5 + 8648389 = 8648394
23 + 8648371 = 8648394
47 + 8648347 = 8648394
61 + 8648333 = 8648394
71 + 8648323 = 8648394
127 + 8648267 = 8648394
173 + 8648221 = 8648394
263 + 8648131 = 8648394

Showing the first eight; more decompositions exist.
