Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502158, here are decompositions:

17 + 502141 = 502158
37 + 502121 = 502158
71 + 502087 = 502158
79 + 502079 = 502158
101 + 502057 = 502158
157 + 502001 = 502158
191 + 501967 = 502158
211 + 501947 = 502158

Showing the first eight; more decompositions exist.
