Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730900, here are decompositions:

7 + 8730893 = 8730900
11 + 8730889 = 8730900
19 + 8730881 = 8730900
37 + 8730863 = 8730900
41 + 8730859 = 8730900
43 + 8730857 = 8730900
53 + 8730847 = 8730900
97 + 8730803 = 8730900

Showing the first eight; more decompositions exist.
