Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626240, here are decompositions:

3 + 8626237 = 8626240
11 + 8626229 = 8626240
59 + 8626181 = 8626240
71 + 8626169 = 8626240
101 + 8626139 = 8626240
131 + 8626109 = 8626240
137 + 8626103 = 8626240
173 + 8626067 = 8626240

Showing the first eight; more decompositions exist.
