Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999554, here are decompositions:

13 + 999541 = 999554
103 + 999451 = 999554
223 + 999331 = 999554
337 + 999217 = 999554
373 + 999181 = 999554
421 + 999133 = 999554
463 + 999091 = 999554
487 + 999067 = 999554

Showing the first eight; more decompositions exist.
