Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626778, here are decompositions:

31 + 8626747 = 8626778
79 + 8626699 = 8626778
109 + 8626669 = 8626778
157 + 8626621 = 8626778
229 + 8626549 = 8626778
271 + 8626507 = 8626778
541 + 8626237 = 8626778
619 + 8626159 = 8626778

Showing the first eight; more decompositions exist.
