Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990948, here are decompositions:

31 + 990917 = 990948
59 + 990889 = 990948
61 + 990887 = 990948
67 + 990881 = 990948
97 + 990851 = 990948
107 + 990841 = 990948
139 + 990809 = 990948
149 + 990799 = 990948

Showing the first eight; more decompositions exist.
