Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528430, here are decompositions:

11 + 528419 = 528430
17 + 528413 = 528430
29 + 528401 = 528430
47 + 528383 = 528430
101 + 528329 = 528430
113 + 528317 = 528430
131 + 528299 = 528430
167 + 528263 = 528430

Showing the first eight; more decompositions exist.
