Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637252, here are decompositions:

5 + 8637247 = 8637252
73 + 8637179 = 8637252
89 + 8637163 = 8637252
101 + 8637151 = 8637252
149 + 8637103 = 8637252
191 + 8637061 = 8637252
193 + 8637059 = 8637252
199 + 8637053 = 8637252

Showing the first eight; more decompositions exist.
