Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8900, here are decompositions:

7 + 8893 = 8900
13 + 8887 = 8900
37 + 8863 = 8900
61 + 8839 = 8900
79 + 8821 = 8900
97 + 8803 = 8900
139 + 8761 = 8900
163 + 8737 = 8900

Showing the first eight; more decompositions exist.
