Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030890, here are decompositions:

17 + 1030873 = 1030890
23 + 1030867 = 1030890
43 + 1030847 = 1030890
59 + 1030831 = 1030890
67 + 1030823 = 1030890
73 + 1030817 = 1030890
79 + 1030811 = 1030890
89 + 1030801 = 1030890

Showing the first eight; more decompositions exist.
