Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999504, here are decompositions:

5 + 999499 = 999504
13 + 999491 = 999504
53 + 999451 = 999504
67 + 999437 = 999504
71 + 999433 = 999504
73 + 999431 = 999504
127 + 999377 = 999504
173 + 999331 = 999504

Showing the first eight; more decompositions exist.
