Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001562, here are decompositions:

11 + 1001551 = 1001562
13 + 1001549 = 1001562
31 + 1001531 = 1001562
61 + 1001501 = 1001562
71 + 1001491 = 1001562
103 + 1001459 = 1001562
131 + 1001431 = 1001562
151 + 1001411 = 1001562

Showing the first eight; more decompositions exist.
