Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77200, here are decompositions:

29 + 77171 = 77200
47 + 77153 = 77200
59 + 77141 = 77200
107 + 77093 = 77200
131 + 77069 = 77200
197 + 77003 = 77200
239 + 76961 = 77200
251 + 76949 = 77200

Showing the first eight; more decompositions exist.
