Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940890, here are decompositions:

11 + 940879 = 940890
19 + 940871 = 940890
37 + 940853 = 940890
61 + 940829 = 940890
73 + 940817 = 940890
89 + 940801 = 940890
103 + 940787 = 940890
107 + 940783 = 940890

Showing the first eight; more decompositions exist.
