Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620690, here are decompositions:

3 + 8620687 = 8620690
17 + 8620673 = 8620690
53 + 8620637 = 8620690
59 + 8620631 = 8620690
101 + 8620589 = 8620690
137 + 8620553 = 8620690
191 + 8620499 = 8620690
383 + 8620307 = 8620690

Showing the first eight; more decompositions exist.
