Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990074, here are decompositions:

31 + 990043 = 990074
37 + 990037 = 990074
61 + 990013 = 990074
73 + 990001 = 990074
97 + 989977 = 990074
103 + 989971 = 990074
157 + 989917 = 990074
271 + 989803 = 990074

Showing the first eight; more decompositions exist.
