Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749818, here are decompositions:

5 + 8749813 = 8749818
29 + 8749789 = 8749818
31 + 8749787 = 8749818
47 + 8749771 = 8749818
67 + 8749751 = 8749818
149 + 8749669 = 8749818
167 + 8749651 = 8749818
191 + 8749627 = 8749818

Showing the first eight; more decompositions exist.
