Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657706, here are decompositions:

7 + 8657699 = 8657706
19 + 8657687 = 8657706
67 + 8657639 = 8657706
73 + 8657633 = 8657706
137 + 8657569 = 8657706
139 + 8657567 = 8657706
149 + 8657557 = 8657706
173 + 8657533 = 8657706

Showing the first eight; more decompositions exist.
