Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749080, here are decompositions:

31 + 8749049 = 8749080
61 + 8749019 = 8749080
73 + 8749007 = 8749080
79 + 8749001 = 8749080
89 + 8748991 = 8749080
101 + 8748979 = 8749080
107 + 8748973 = 8749080
127 + 8748953 = 8749080

Showing the first eight; more decompositions exist.
