Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613900, here are decompositions:

7 + 8613893 = 8613900
13 + 8613887 = 8613900
37 + 8613863 = 8613900
47 + 8613853 = 8613900
73 + 8613827 = 8613900
83 + 8613817 = 8613900
89 + 8613811 = 8613900
103 + 8613797 = 8613900

Showing the first eight; more decompositions exist.
