Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999528, here are decompositions:

7 + 999521 = 999528
29 + 999499 = 999528
37 + 999491 = 999528
97 + 999431 = 999528
139 + 999389 = 999528
151 + 999377 = 999528
157 + 999371 = 999528
197 + 999331 = 999528

Showing the first eight; more decompositions exist.
