Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528278, here are decompositions:

31 + 528247 = 528278
61 + 528217 = 528278
151 + 528127 = 528278
181 + 528097 = 528278
277 + 528001 = 528278
337 + 527941 = 528278
349 + 527929 = 528278
397 + 527881 = 528278

Showing the first eight; more decompositions exist.
