Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618806, here are decompositions:

17 + 8618789 = 8618806
23 + 8618783 = 8618806
47 + 8618759 = 8618806
59 + 8618747 = 8618806
107 + 8618699 = 8618806
167 + 8618639 = 8618806
239 + 8618567 = 8618806
419 + 8618387 = 8618806

Showing the first eight; more decompositions exist.
