Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528446, here are decompositions:

13 + 528433 = 528446
43 + 528403 = 528446
73 + 528373 = 528446
157 + 528289 = 528446
199 + 528247 = 528446
223 + 528223 = 528446
229 + 528217 = 528446
283 + 528163 = 528446

Showing the first eight; more decompositions exist.
