Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637250, here are decompositions:

3 + 8637247 = 8637250
23 + 8637227 = 8637250
47 + 8637203 = 8637250
71 + 8637179 = 8637250
131 + 8637119 = 8637250
191 + 8637059 = 8637250
197 + 8637053 = 8637250
233 + 8637017 = 8637250

Showing the first eight; more decompositions exist.
