Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528938, here are decompositions:

61 + 528877 = 528938
127 + 528811 = 528938
139 + 528799 = 528938
229 + 528709 = 528938
271 + 528667 = 528938
307 + 528631 = 528938
379 + 528559 = 528938
547 + 528391 = 528938

Showing the first eight; more decompositions exist.
