Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528390, here are decompositions:

7 + 528383 = 528390
17 + 528373 = 528390
61 + 528329 = 528390
73 + 528317 = 528390
101 + 528289 = 528390
127 + 528263 = 528390
167 + 528223 = 528390
173 + 528217 = 528390

Showing the first eight; more decompositions exist.
