Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001556, here are decompositions:

5 + 1001551 = 1001556
7 + 1001549 = 1001556
29 + 1001527 = 1001556
89 + 1001467 = 1001556
97 + 1001459 = 1001556
109 + 1001447 = 1001556
167 + 1001389 = 1001556
229 + 1001327 = 1001556

Showing the first eight; more decompositions exist.
