Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990624, here are decompositions:

31 + 990593 = 990624
101 + 990523 = 990624
113 + 990511 = 990624
127 + 990497 = 990624
137 + 990487 = 990624
227 + 990397 = 990624
241 + 990383 = 990624
263 + 990361 = 990624

Showing the first eight; more decompositions exist.
