Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77260, here are decompositions:

11 + 77249 = 77260
17 + 77243 = 77260
23 + 77237 = 77260
47 + 77213 = 77260
59 + 77201 = 77260
89 + 77171 = 77260
107 + 77153 = 77260
167 + 77093 = 77260

Showing the first eight; more decompositions exist.
