Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528458, here are decompositions:

67 + 528391 = 528458
211 + 528247 = 528458
241 + 528217 = 528458
331 + 528127 = 528458
367 + 528091 = 528458
457 + 528001 = 528458
577 + 527881 = 528458
607 + 527851 = 528458

Showing the first eight; more decompositions exist.
