Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990542, here are decompositions:

13 + 990529 = 990542
19 + 990523 = 990542
31 + 990511 = 990542
73 + 990469 = 990542
79 + 990463 = 990542
181 + 990361 = 990542
193 + 990349 = 990542
211 + 990331 = 990542

Showing the first eight; more decompositions exist.
