Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990834, here are decompositions:

37 + 990797 = 990834
67 + 990767 = 990834
73 + 990761 = 990834
101 + 990733 = 990834
127 + 990707 = 990834
191 + 990643 = 990834
197 + 990637 = 990834
241 + 990593 = 990834

Showing the first eight; more decompositions exist.
