Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001658, here are decompositions:

19 + 1001639 = 1001658
29 + 1001629 = 1001658
37 + 1001621 = 1001658
71 + 1001587 = 1001658
89 + 1001569 = 1001658
107 + 1001551 = 1001658
109 + 1001549 = 1001658
127 + 1001531 = 1001658

Showing the first eight; more decompositions exist.
