Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003782, here are decompositions:

11 + 1003771 = 1003782
19 + 1003763 = 1003782
29 + 1003753 = 1003782
41 + 1003741 = 1003782
53 + 1003729 = 1003782
71 + 1003711 = 1003782
89 + 1003693 = 1003782
103 + 1003679 = 1003782

Showing the first eight; more decompositions exist.
