Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637500, here are decompositions:

7 + 8637493 = 8637500
19 + 8637481 = 8637500
73 + 8637427 = 8637500
127 + 8637373 = 8637500
163 + 8637337 = 8637500
181 + 8637319 = 8637500
199 + 8637301 = 8637500
211 + 8637289 = 8637500

Showing the first eight; more decompositions exist.
