Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990894, here are decompositions:

5 + 990889 = 990894
7 + 990887 = 990894
13 + 990881 = 990894
43 + 990851 = 990894
53 + 990841 = 990894
97 + 990797 = 990894
127 + 990767 = 990894
251 + 990643 = 990894

Showing the first eight; more decompositions exist.
