Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990354, here are decompositions:

5 + 990349 = 990354
23 + 990331 = 990354
31 + 990323 = 990354
41 + 990313 = 990354
47 + 990307 = 990354
61 + 990293 = 990354
67 + 990287 = 990354
73 + 990281 = 990354

Showing the first eight; more decompositions exist.
