Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749878, here are decompositions:

31 + 8749847 = 8749878
37 + 8749841 = 8749878
41 + 8749837 = 8749878
61 + 8749817 = 8749878
89 + 8749789 = 8749878
107 + 8749771 = 8749878
127 + 8749751 = 8749878
227 + 8749651 = 8749878

Showing the first eight; more decompositions exist.
