Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999512, here are decompositions:

13 + 999499 = 999512
61 + 999451 = 999512
79 + 999433 = 999512
181 + 999331 = 999512
313 + 999199 = 999512
331 + 999181 = 999512
379 + 999133 = 999512
421 + 999091 = 999512

Showing the first eight; more decompositions exist.
