Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999530, here are decompositions:

31 + 999499 = 999530
79 + 999451 = 999530
97 + 999433 = 999530
199 + 999331 = 999530
223 + 999307 = 999530
313 + 999217 = 999530
331 + 999199 = 999530
349 + 999181 = 999530

Showing the first eight; more decompositions exist.
