Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990396, here are decompositions:

7 + 990389 = 990396
13 + 990383 = 990396
19 + 990377 = 990396
37 + 990359 = 990396
47 + 990349 = 990396
67 + 990329 = 990396
73 + 990323 = 990396
83 + 990313 = 990396

Showing the first eight; more decompositions exist.
