Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618458, here are decompositions:

29 + 8618429 = 8618458
71 + 8618387 = 8618458
131 + 8618327 = 8618458
311 + 8618147 = 8618458
467 + 8617991 = 8618458
509 + 8617949 = 8618458
587 + 8617871 = 8618458
659 + 8617799 = 8618458

Showing the first eight; more decompositions exist.
