Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984990, here are decompositions:

31 + 984959 = 984990
43 + 984947 = 984990
59 + 984931 = 984990
67 + 984923 = 984990
73 + 984917 = 984990
79 + 984911 = 984990
109 + 984881 = 984990
113 + 984877 = 984990

Showing the first eight; more decompositions exist.
