Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637232, here are decompositions:

5 + 8637227 = 8637232
29 + 8637203 = 8637232
53 + 8637179 = 8637232
101 + 8637131 = 8637232
113 + 8637119 = 8637232
173 + 8637059 = 8637232
179 + 8637053 = 8637232
311 + 8636921 = 8637232

Showing the first eight; more decompositions exist.
