Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67400, here are decompositions:

31 + 67369 = 67400
61 + 67339 = 67400
127 + 67273 = 67400
139 + 67261 = 67400
181 + 67219 = 67400
211 + 67189 = 67400
271 + 67129 = 67400
367 + 67033 = 67400

Showing the first eight; more decompositions exist.
