Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528158, here are decompositions:

31 + 528127 = 528158
61 + 528097 = 528158
67 + 528091 = 528158
157 + 528001 = 528158
229 + 527929 = 528158
277 + 527881 = 528158
307 + 527851 = 528158
349 + 527809 = 528158

Showing the first eight; more decompositions exist.
