Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701668, here are decompositions:

11 + 8701657 = 8701668
37 + 8701631 = 8701668
47 + 8701621 = 8701668
97 + 8701571 = 8701668
109 + 8701559 = 8701668
137 + 8701531 = 8701668
139 + 8701529 = 8701668
149 + 8701519 = 8701668

Showing the first eight; more decompositions exist.
