Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990898, here are decompositions:

5 + 990893 = 990898
11 + 990887 = 990898
17 + 990881 = 990898
47 + 990851 = 990898
89 + 990809 = 990898
101 + 990797 = 990898
131 + 990767 = 990898
137 + 990761 = 990898

Showing the first eight; more decompositions exist.
