Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8200, here are decompositions:

29 + 8171 = 8200
53 + 8147 = 8200
83 + 8117 = 8200
89 + 8111 = 8200
107 + 8093 = 8200
113 + 8087 = 8200
131 + 8069 = 8200
191 + 8009 = 8200

Showing the first eight; more decompositions exist.
