Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706620, here are decompositions:

7 + 8706613 = 8706620
67 + 8706553 = 8706620
73 + 8706547 = 8706620
157 + 8706463 = 8706620
163 + 8706457 = 8706620
271 + 8706349 = 8706620
283 + 8706337 = 8706620
331 + 8706289 = 8706620

Showing the first eight; more decompositions exist.
