Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001518, here are decompositions:

17 + 1001501 = 1001518
59 + 1001459 = 1001518
71 + 1001447 = 1001518
107 + 1001411 = 1001518
131 + 1001387 = 1001518
137 + 1001381 = 1001518
149 + 1001369 = 1001518
191 + 1001327 = 1001518

Showing the first eight; more decompositions exist.
