Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999458, here are decompositions:

7 + 999451 = 999458
127 + 999331 = 999458
151 + 999307 = 999458
241 + 999217 = 999458
277 + 999181 = 999458
367 + 999091 = 999458
409 + 999049 = 999458
541 + 998917 = 999458

Showing the first eight; more decompositions exist.
