Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001478, here are decompositions:

11 + 1001467 = 1001478
19 + 1001459 = 1001478
31 + 1001447 = 1001478
47 + 1001431 = 1001478
67 + 1001411 = 1001478
89 + 1001389 = 1001478
97 + 1001381 = 1001478
109 + 1001369 = 1001478

Showing the first eight; more decompositions exist.
