Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637328, here are decompositions:

5 + 8637323 = 8637328
17 + 8637311 = 8637328
71 + 8637257 = 8637328
101 + 8637227 = 8637328
149 + 8637179 = 8637328
197 + 8637131 = 8637328
269 + 8637059 = 8637328
311 + 8637017 = 8637328

Showing the first eight; more decompositions exist.
