Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77458, here are decompositions:

11 + 77447 = 77458
41 + 77417 = 77458
89 + 77369 = 77458
107 + 77351 = 77458
167 + 77291 = 77458
179 + 77279 = 77458
191 + 77267 = 77458
197 + 77261 = 77458

Showing the first eight; more decompositions exist.
