Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648400, here are decompositions:

11 + 8648389 = 8648400
29 + 8648371 = 8648400
31 + 8648369 = 8648400
53 + 8648347 = 8648400
67 + 8648333 = 8648400
83 + 8648317 = 8648400
149 + 8648251 = 8648400
179 + 8648221 = 8648400

Showing the first eight; more decompositions exist.
