Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990892, here are decompositions:

3 + 990889 = 990892
5 + 990887 = 990892
11 + 990881 = 990892
41 + 990851 = 990892
83 + 990809 = 990892
131 + 990761 = 990892
173 + 990719 = 990892
293 + 990599 = 990892

Showing the first eight; more decompositions exist.
