Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749782, here are decompositions:

11 + 8749771 = 8749782
29 + 8749753 = 8749782
31 + 8749751 = 8749782
113 + 8749669 = 8749782
131 + 8749651 = 8749782
179 + 8749603 = 8749782
193 + 8749589 = 8749782
211 + 8749571 = 8749782

Showing the first eight; more decompositions exist.
