Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003788, here are decompositions:

17 + 1003771 = 1003788
31 + 1003757 = 1003788
41 + 1003747 = 1003788
47 + 1003741 = 1003788
59 + 1003729 = 1003788
109 + 1003679 = 1003788
157 + 1003631 = 1003788
167 + 1003621 = 1003788

Showing the first eight; more decompositions exist.
