Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77274, here are decompositions:

5 + 77269 = 77274
7 + 77267 = 77274
11 + 77263 = 77274
13 + 77261 = 77274
31 + 77243 = 77274
37 + 77237 = 77274
61 + 77213 = 77274
73 + 77201 = 77274

Showing the first eight; more decompositions exist.
