Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989892, here are decompositions:

5 + 989887 = 989892
19 + 989873 = 989892
23 + 989869 = 989892
53 + 989839 = 989892
61 + 989831 = 989892
89 + 989803 = 989892
109 + 989783 = 989892
131 + 989761 = 989892

Showing the first eight; more decompositions exist.
