Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749800, here are decompositions:

11 + 8749789 = 8749800
13 + 8749787 = 8749800
29 + 8749771 = 8749800
47 + 8749753 = 8749800
67 + 8749733 = 8749800
131 + 8749669 = 8749800
149 + 8749651 = 8749800
173 + 8749627 = 8749800

Showing the first eight; more decompositions exist.
