Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77250, here are decompositions:

7 + 77243 = 77250
11 + 77239 = 77250
13 + 77237 = 77250
37 + 77213 = 77250
59 + 77191 = 77250
79 + 77171 = 77250
83 + 77167 = 77250
97 + 77153 = 77250

Showing the first eight; more decompositions exist.
