Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528040, here are decompositions:

47 + 527993 = 528040
53 + 527987 = 528040
59 + 527981 = 528040
131 + 527909 = 528040
197 + 527843 = 528040
251 + 527789 = 528040
311 + 527729 = 528040
449 + 527591 = 528040

Showing the first eight; more decompositions exist.
