Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717782, here are decompositions:

41 + 8717741 = 8717782
149 + 8717633 = 8717782
191 + 8717591 = 8717782
251 + 8717531 = 8717782
389 + 8717393 = 8717782
509 + 8717273 = 8717782
569 + 8717213 = 8717782
659 + 8717123 = 8717782

Showing the first eight; more decompositions exist.
