Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76400, here are decompositions:

13 + 76387 = 76400
31 + 76369 = 76400
67 + 76333 = 76400
97 + 76303 = 76400
139 + 76261 = 76400
151 + 76249 = 76400
157 + 76243 = 76400
193 + 76207 = 76400

Showing the first eight; more decompositions exist.
