Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984890, here are decompositions:

13 + 984877 = 984890
31 + 984859 = 984890
37 + 984853 = 984890
43 + 984847 = 984890
73 + 984817 = 984890
157 + 984733 = 984890
223 + 984667 = 984890
307 + 984583 = 984890

Showing the first eight; more decompositions exist.
