Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528248, here are decompositions:

31 + 528217 = 528248
151 + 528097 = 528248
157 + 528091 = 528248
307 + 527941 = 528248
367 + 527881 = 528248
379 + 527869 = 528248
397 + 527851 = 528248
439 + 527809 = 528248

Showing the first eight; more decompositions exist.
