Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989928, here are decompositions:

7 + 989921 = 989928
11 + 989917 = 989928
19 + 989909 = 989928
41 + 989887 = 989928
59 + 989869 = 989928
89 + 989839 = 989928
97 + 989831 = 989928
101 + 989827 = 989928

Showing the first eight; more decompositions exist.
