Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637208, here are decompositions:

5 + 8637203 = 8637208
29 + 8637179 = 8637208
89 + 8637119 = 8637208
101 + 8637107 = 8637208
149 + 8637059 = 8637208
191 + 8637017 = 8637208
389 + 8636819 = 8637208
449 + 8636759 = 8637208

Showing the first eight; more decompositions exist.
