Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648406, here are decompositions:

17 + 8648389 = 8648406
37 + 8648369 = 8648406
59 + 8648347 = 8648406
73 + 8648333 = 8648406
83 + 8648323 = 8648406
89 + 8648317 = 8648406
139 + 8648267 = 8648406
167 + 8648239 = 8648406

Showing the first eight; more decompositions exist.
