Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990924, here are decompositions:

7 + 990917 = 990924
31 + 990893 = 990924
37 + 990887 = 990924
43 + 990881 = 990924
73 + 990851 = 990924
83 + 990841 = 990924
127 + 990797 = 990924
157 + 990767 = 990924

Showing the first eight; more decompositions exist.
