Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964890, here are decompositions:

7 + 964883 = 964890
11 + 964879 = 964890
19 + 964871 = 964890
29 + 964861 = 964890
61 + 964829 = 964890
67 + 964823 = 964890
97 + 964793 = 964890
103 + 964787 = 964890

Showing the first eight; more decompositions exist.
