Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672900, here are decompositions:

3 + 8672897 = 8672900
31 + 8672869 = 8672900
79 + 8672821 = 8672900
109 + 8672791 = 8672900
127 + 8672773 = 8672900
193 + 8672707 = 8672900
241 + 8672659 = 8672900
337 + 8672563 = 8672900

Showing the first eight; more decompositions exist.
