Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626782, here are decompositions:

5 + 8626777 = 8626782
19 + 8626763 = 8626782
83 + 8626699 = 8626782
113 + 8626669 = 8626782
139 + 8626643 = 8626782
179 + 8626603 = 8626782
233 + 8626549 = 8626782
313 + 8626469 = 8626782

Showing the first eight; more decompositions exist.
