Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749908, here are decompositions:

5 + 8749903 = 8749908
17 + 8749891 = 8749908
61 + 8749847 = 8749908
67 + 8749841 = 8749908
71 + 8749837 = 8749908
137 + 8749771 = 8749908
157 + 8749751 = 8749908
239 + 8749669 = 8749908

Showing the first eight; more decompositions exist.
