Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749902, here are decompositions:

11 + 8749891 = 8749902
61 + 8749841 = 8749902
89 + 8749813 = 8749902
113 + 8749789 = 8749902
131 + 8749771 = 8749902
149 + 8749753 = 8749902
151 + 8749751 = 8749902
233 + 8749669 = 8749902

Showing the first eight; more decompositions exist.
