Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654620, here are decompositions:

3 + 8654617 = 8654620
11 + 8654609 = 8654620
41 + 8654579 = 8654620
47 + 8654573 = 8654620
131 + 8654489 = 8654620
137 + 8654483 = 8654620
167 + 8654453 = 8654620
173 + 8654447 = 8654620

Showing the first eight; more decompositions exist.
