Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001790, here are decompositions:

7 + 1001783 = 1001790
47 + 1001743 = 1001790
67 + 1001723 = 1001790
103 + 1001687 = 1001790
107 + 1001683 = 1001790
131 + 1001659 = 1001790
151 + 1001639 = 1001790
197 + 1001593 = 1001790

Showing the first eight; more decompositions exist.
