Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7400, here are decompositions:

7 + 7393 = 7400
31 + 7369 = 7400
67 + 7333 = 7400
79 + 7321 = 7400
103 + 7297 = 7400
157 + 7243 = 7400
163 + 7237 = 7400
181 + 7219 = 7400

Showing the first eight; more decompositions exist.
