Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999408, here are decompositions:

19 + 999389 = 999408
31 + 999377 = 999408
37 + 999371 = 999408
79 + 999329 = 999408
101 + 999307 = 999408
139 + 999269 = 999408
191 + 999217 = 999408
227 + 999181 = 999408

Showing the first eight; more decompositions exist.
