Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724900, here are decompositions:

17 + 8724883 = 8724900
29 + 8724871 = 8724900
53 + 8724847 = 8724900
73 + 8724827 = 8724900
97 + 8724803 = 8724900
101 + 8724799 = 8724900
113 + 8724787 = 8724900
179 + 8724721 = 8724900

Showing the first eight; more decompositions exist.
