Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990882, here are decompositions:

31 + 990851 = 990882
41 + 990841 = 990882
73 + 990809 = 990882
83 + 990799 = 990882
149 + 990733 = 990882
163 + 990719 = 990882
239 + 990643 = 990882
251 + 990631 = 990882

Showing the first eight; more decompositions exist.
