Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136400, here are decompositions:

3 + 136397 = 136400
7 + 136393 = 136400
67 + 136333 = 136400
73 + 136327 = 136400
97 + 136303 = 136400
127 + 136273 = 136400
139 + 136261 = 136400
163 + 136237 = 136400

Showing the first eight; more decompositions exist.
