Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502398, here are decompositions:

5 + 502393 = 502398
59 + 502339 = 502398
97 + 502301 = 502398
137 + 502261 = 502398
139 + 502259 = 502398
151 + 502247 = 502398
181 + 502217 = 502398
227 + 502171 = 502398

Showing the first eight; more decompositions exist.
