Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001458, here are decompositions:

11 + 1001447 = 1001458
47 + 1001411 = 1001458
71 + 1001387 = 1001458
89 + 1001369 = 1001458
131 + 1001327 = 1001458
137 + 1001321 = 1001458
167 + 1001291 = 1001458
179 + 1001279 = 1001458

Showing the first eight; more decompositions exist.
