Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990974, here are decompositions:

7 + 990967 = 990974
13 + 990961 = 990974
241 + 990733 = 990974
331 + 990643 = 990974
337 + 990637 = 990974
463 + 990511 = 990974
487 + 990487 = 990974
577 + 990397 = 990974

Showing the first eight; more decompositions exist.
