Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624800, here are decompositions:

29 + 8624771 = 8624800
47 + 8624753 = 8624800
83 + 8624717 = 8624800
131 + 8624669 = 8624800
167 + 8624633 = 8624800
179 + 8624621 = 8624800
227 + 8624573 = 8624800
293 + 8624507 = 8624800

Showing the first eight; more decompositions exist.
