Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990904, here are decompositions:

11 + 990893 = 990904
17 + 990887 = 990904
23 + 990881 = 990904
53 + 990851 = 990904
107 + 990797 = 990904
137 + 990767 = 990904
197 + 990707 = 990904
311 + 990593 = 990904

Showing the first eight; more decompositions exist.
