Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990928, here are decompositions:

5 + 990923 = 990928
11 + 990917 = 990928
41 + 990887 = 990928
47 + 990881 = 990928
131 + 990797 = 990928
167 + 990761 = 990928
431 + 990497 = 990928
557 + 990371 = 990928

Showing the first eight; more decompositions exist.
