Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76388, here are decompositions:

19 + 76369 = 76388
127 + 76261 = 76388
139 + 76249 = 76388
157 + 76231 = 76388
181 + 76207 = 76388
229 + 76159 = 76388
241 + 76147 = 76388
307 + 76081 = 76388

Showing the first eight; more decompositions exist.
