Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502400, here are decompositions:

7 + 502393 = 502400
61 + 502339 = 502400
79 + 502321 = 502400
139 + 502261 = 502400
163 + 502237 = 502400
229 + 502171 = 502400
307 + 502093 = 502400
313 + 502087 = 502400

Showing the first eight; more decompositions exist.
