Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706458, here are decompositions:

97 + 8706361 = 8706458
109 + 8706349 = 8706458
181 + 8706277 = 8706458
379 + 8706079 = 8706458
457 + 8706001 = 8706458
499 + 8705959 = 8706458
547 + 8705911 = 8706458
577 + 8705881 = 8706458

Showing the first eight; more decompositions exist.
