Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528272, here are decompositions:

109 + 528163 = 528272
181 + 528091 = 528272
229 + 528043 = 528272
271 + 528001 = 528272
331 + 527941 = 528272
421 + 527851 = 528272
463 + 527809 = 528272
523 + 527749 = 528272

Showing the first eight; more decompositions exist.
