Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528330, here are decompositions:

13 + 528317 = 528330
17 + 528313 = 528330
31 + 528299 = 528330
41 + 528289 = 528330
67 + 528263 = 528330
83 + 528247 = 528330
107 + 528223 = 528330
113 + 528217 = 528330

Showing the first eight; more decompositions exist.
