Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77258, here are decompositions:

19 + 77239 = 77258
67 + 77191 = 77258
157 + 77101 = 77258
211 + 77047 = 77258
229 + 77029 = 77258
241 + 77017 = 77258
421 + 76837 = 77258
439 + 76819 = 77258

Showing the first eight; more decompositions exist.
