Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528530, here are decompositions:

3 + 528527 = 528530
19 + 528511 = 528530
43 + 528487 = 528530
61 + 528469 = 528530
97 + 528433 = 528530
127 + 528403 = 528530
139 + 528391 = 528530
157 + 528373 = 528530

Showing the first eight; more decompositions exist.
