Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1200, here are decompositions:

7 + 1193 = 1200
13 + 1187 = 1200
19 + 1181 = 1200
29 + 1171 = 1200
37 + 1163 = 1200
47 + 1153 = 1200
71 + 1129 = 1200
83 + 1117 = 1200

Showing the first eight; more decompositions exist.
