Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634520, here are decompositions:

3 + 8634517 = 8634520
17 + 8634503 = 8634520
23 + 8634497 = 8634520
53 + 8634467 = 8634520
71 + 8634449 = 8634520
107 + 8634413 = 8634520
137 + 8634383 = 8634520
149 + 8634371 = 8634520

Showing the first eight; more decompositions exist.
