Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648622, here are decompositions:

71 + 8648551 = 8648622
79 + 8648543 = 8648622
89 + 8648533 = 8648622
109 + 8648513 = 8648622
163 + 8648459 = 8648622
233 + 8648389 = 8648622
251 + 8648371 = 8648622
383 + 8648239 = 8648622

Showing the first eight; more decompositions exist.
