Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708620, here are decompositions:

3 + 8708617 = 8708620
29 + 8708591 = 8708620
83 + 8708537 = 8708620
101 + 8708519 = 8708620
113 + 8708507 = 8708620
191 + 8708429 = 8708620
197 + 8708423 = 8708620
227 + 8708393 = 8708620

Showing the first eight; more decompositions exist.
