Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999548, here are decompositions:

7 + 999541 = 999548
19 + 999529 = 999548
97 + 999451 = 999548
241 + 999307 = 999548
331 + 999217 = 999548
349 + 999199 = 999548
367 + 999181 = 999548
379 + 999169 = 999548

Showing the first eight; more decompositions exist.
