Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758458, here are decompositions:

11 + 8758447 = 8758458
29 + 8758429 = 8758458
31 + 8758427 = 8758458
67 + 8758391 = 8758458
97 + 8758361 = 8758458
131 + 8758327 = 8758458
179 + 8758279 = 8758458
229 + 8758229 = 8758458

Showing the first eight; more decompositions exist.
