Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2200, here are decompositions:

47 + 2153 = 2200
59 + 2141 = 2200
71 + 2129 = 2200
89 + 2111 = 2200
101 + 2099 = 2200
113 + 2087 = 2200
131 + 2069 = 2200
137 + 2063 = 2200

Showing the first eight; more decompositions exist.
