Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657782, here are decompositions:

11 + 8657771 = 8657782
59 + 8657723 = 8657782
83 + 8657699 = 8657782
101 + 8657681 = 8657782
131 + 8657651 = 8657782
149 + 8657633 = 8657782
269 + 8657513 = 8657782
359 + 8657423 = 8657782

Showing the first eight; more decompositions exist.
