Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626578, here are decompositions:

29 + 8626549 = 8626578
61 + 8626517 = 8626578
71 + 8626507 = 8626578
109 + 8626469 = 8626578
157 + 8626421 = 8626578
229 + 8626349 = 8626578
277 + 8626301 = 8626578
281 + 8626297 = 8626578

Showing the first eight; more decompositions exist.
