Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013966, here are decompositions:

43 + 1013923 = 1013966
67 + 1013899 = 1013966
73 + 1013893 = 1013966
127 + 1013839 = 1013966
139 + 1013827 = 1013966
193 + 1013773 = 1013966
199 + 1013767 = 1013966
337 + 1013629 = 1013966

Showing the first eight; more decompositions exist.
