Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528878, here are decompositions:

67 + 528811 = 528878
79 + 528799 = 528878
199 + 528679 = 528878
211 + 528667 = 528878
367 + 528511 = 528878
409 + 528469 = 528878
487 + 528391 = 528878
631 + 528247 = 528878

Showing the first eight; more decompositions exist.
