Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632428, here are decompositions:

5 + 8632423 = 8632428
17 + 8632411 = 8632428
29 + 8632399 = 8632428
37 + 8632391 = 8632428
41 + 8632387 = 8632428
47 + 8632381 = 8632428
61 + 8632367 = 8632428
67 + 8632361 = 8632428

Showing the first eight; more decompositions exist.
