Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003986, here are decompositions:

23 + 1003963 = 1003986
29 + 1003957 = 1003986
43 + 1003943 = 1003986
73 + 1003913 = 1003986
79 + 1003907 = 1003986
89 + 1003897 = 1003986
97 + 1003889 = 1003986
107 + 1003879 = 1003986

Showing the first eight; more decompositions exist.
