Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626780, here are decompositions:

3 + 8626777 = 8626780
17 + 8626763 = 8626780
47 + 8626733 = 8626780
83 + 8626697 = 8626780
89 + 8626691 = 8626780
137 + 8626643 = 8626780
167 + 8626613 = 8626780
251 + 8626529 = 8626780

Showing the first eight; more decompositions exist.
