Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041990, here are decompositions:

7 + 1041983 = 1041990
29 + 1041961 = 1041990
41 + 1041949 = 1041990
71 + 1041919 = 1041990
83 + 1041907 = 1041990
97 + 1041893 = 1041990
101 + 1041889 = 1041990
127 + 1041863 = 1041990

Showing the first eight; more decompositions exist.
