Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528470, here are decompositions:

37 + 528433 = 528470
67 + 528403 = 528470
79 + 528391 = 528470
97 + 528373 = 528470
157 + 528313 = 528470
181 + 528289 = 528470
223 + 528247 = 528470
307 + 528163 = 528470

Showing the first eight; more decompositions exist.
