Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999506, here are decompositions:

7 + 999499 = 999506
73 + 999433 = 999506
199 + 999307 = 999506
307 + 999199 = 999506
337 + 999169 = 999506
373 + 999133 = 999506
439 + 999067 = 999506
457 + 999049 = 999506

Showing the first eight; more decompositions exist.
