Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999540, here are decompositions:

11 + 999529 = 999540
19 + 999521 = 999540
41 + 999499 = 999540
89 + 999451 = 999540
103 + 999437 = 999540
107 + 999433 = 999540
109 + 999431 = 999540
151 + 999389 = 999540

Showing the first eight; more decompositions exist.
