Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528242, here are decompositions:

19 + 528223 = 528242
79 + 528163 = 528242
151 + 528091 = 528242
199 + 528043 = 528242
229 + 528013 = 528242
241 + 528001 = 528242
313 + 527929 = 528242
373 + 527869 = 528242

Showing the first eight; more decompositions exist.
