Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77248, here are decompositions:

5 + 77243 = 77248
11 + 77237 = 77248
47 + 77201 = 77248
107 + 77141 = 77248
167 + 77081 = 77248
179 + 77069 = 77248
257 + 76991 = 77248
401 + 76847 = 77248

Showing the first eight; more decompositions exist.
