Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990912, here are decompositions:

19 + 990893 = 990912
23 + 990889 = 990912
31 + 990881 = 990912
61 + 990851 = 990912
71 + 990841 = 990912
103 + 990809 = 990912
113 + 990799 = 990912
151 + 990761 = 990912

Showing the first eight; more decompositions exist.
