Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741808, here are decompositions:

7 + 8741801 = 8741808
11 + 8741797 = 8741808
29 + 8741779 = 8741808
59 + 8741749 = 8741808
67 + 8741741 = 8741808
109 + 8741699 = 8741808
167 + 8741641 = 8741808
199 + 8741609 = 8741808

Showing the first eight; more decompositions exist.
