Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528998, here are decompositions:

7 + 528991 = 528998
31 + 528967 = 528998
199 + 528799 = 528998
307 + 528691 = 528998
331 + 528667 = 528998
367 + 528631 = 528998
439 + 528559 = 528998
487 + 528511 = 528998

Showing the first eight; more decompositions exist.
