Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502178, here are decompositions:

7 + 502171 = 502178
37 + 502141 = 502178
97 + 502081 = 502178
139 + 502039 = 502178
181 + 501997 = 502178
211 + 501967 = 502178
337 + 501841 = 502178
349 + 501829 = 502178

Showing the first eight; more decompositions exist.
