Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990916, here are decompositions:

23 + 990893 = 990916
29 + 990887 = 990916
107 + 990809 = 990916
149 + 990767 = 990916
197 + 990719 = 990916
317 + 990599 = 990916
419 + 990497 = 990916
557 + 990359 = 990916

Showing the first eight; more decompositions exist.
