Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637240, here are decompositions:

13 + 8637227 = 8637240
37 + 8637203 = 8637240
61 + 8637179 = 8637240
89 + 8637151 = 8637240
107 + 8637133 = 8637240
109 + 8637131 = 8637240
137 + 8637103 = 8637240
149 + 8637091 = 8637240

Showing the first eight; more decompositions exist.
