Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017990, here are decompositions:

31 + 1017959 = 1017990
37 + 1017953 = 1017990
67 + 1017923 = 1017990
101 + 1017889 = 1017990
109 + 1017881 = 1017990
131 + 1017859 = 1017990
139 + 1017851 = 1017990
163 + 1017827 = 1017990

Showing the first eight; more decompositions exist.
