Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708866, here are decompositions:

17 + 8708849 = 8708866
59 + 8708807 = 8708866
149 + 8708717 = 8708866
227 + 8708639 = 8708866
239 + 8708627 = 8708866
347 + 8708519 = 8708866
359 + 8708507 = 8708866
443 + 8708423 = 8708866

Showing the first eight; more decompositions exist.
