Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626278, here are decompositions:

7 + 8626271 = 8626278
29 + 8626249 = 8626278
41 + 8626237 = 8626278
97 + 8626181 = 8626278
109 + 8626169 = 8626278
137 + 8626141 = 8626278
139 + 8626139 = 8626278
149 + 8626129 = 8626278

Showing the first eight; more decompositions exist.
