Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634900, here are decompositions:

11 + 8634889 = 8634900
17 + 8634883 = 8634900
19 + 8634881 = 8634900
37 + 8634863 = 8634900
41 + 8634859 = 8634900
59 + 8634841 = 8634900
61 + 8634839 = 8634900
89 + 8634811 = 8634900

Showing the first eight; more decompositions exist.
