Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655658, here are decompositions:

5 + 8655653 = 8655658
17 + 8655641 = 8655658
29 + 8655629 = 8655658
47 + 8655611 = 8655658
131 + 8655527 = 8655658
257 + 8655401 = 8655658
461 + 8655197 = 8655658
491 + 8655167 = 8655658

Showing the first eight; more decompositions exist.
