Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77290, here are decompositions:

11 + 77279 = 77290
23 + 77267 = 77290
29 + 77261 = 77290
41 + 77249 = 77290
47 + 77243 = 77290
53 + 77237 = 77290
89 + 77201 = 77290
137 + 77153 = 77290

Showing the first eight; more decompositions exist.
