Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748900, here are decompositions:

7 + 8748893 = 8748900
11 + 8748889 = 8748900
19 + 8748881 = 8748900
23 + 8748877 = 8748900
47 + 8748853 = 8748900
53 + 8748847 = 8748900
59 + 8748841 = 8748900
73 + 8748827 = 8748900

Showing the first eight; more decompositions exist.
