Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751900, here are decompositions:

13 + 8751887 = 8751900
29 + 8751871 = 8751900
37 + 8751863 = 8751900
41 + 8751859 = 8751900
61 + 8751839 = 8751900
71 + 8751829 = 8751900
83 + 8751817 = 8751900
97 + 8751803 = 8751900

Showing the first eight; more decompositions exist.
