Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626740, here are decompositions:

7 + 8626733 = 8626740
41 + 8626699 = 8626740
43 + 8626697 = 8626740
71 + 8626669 = 8626740
97 + 8626643 = 8626740
127 + 8626613 = 8626740
137 + 8626603 = 8626740
163 + 8626577 = 8626740

Showing the first eight; more decompositions exist.
