Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999444, here are decompositions:

7 + 999437 = 999444
11 + 999433 = 999444
13 + 999431 = 999444
67 + 999377 = 999444
73 + 999371 = 999444
113 + 999331 = 999444
137 + 999307 = 999444
157 + 999287 = 999444

Showing the first eight; more decompositions exist.
