Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528308, here are decompositions:

19 + 528289 = 528308
61 + 528247 = 528308
181 + 528127 = 528308
211 + 528097 = 528308
307 + 528001 = 528308
367 + 527941 = 528308
379 + 527929 = 528308
439 + 527869 = 528308

Showing the first eight; more decompositions exist.
