Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990844, here are decompositions:

3 + 990841 = 990844
47 + 990797 = 990844
83 + 990761 = 990844
137 + 990707 = 990844
251 + 990593 = 990844
347 + 990497 = 990844
461 + 990383 = 990844
467 + 990377 = 990844

Showing the first eight; more decompositions exist.
