Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755458, here are decompositions:

7 + 8755451 = 8755458
59 + 8755399 = 8755458
79 + 8755379 = 8755458
109 + 8755349 = 8755458
137 + 8755321 = 8755458
139 + 8755319 = 8755458
167 + 8755291 = 8755458
181 + 8755277 = 8755458

Showing the first eight; more decompositions exist.
