Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620626, here are decompositions:

5 + 8620621 = 8620626
23 + 8620603 = 8620626
37 + 8620589 = 8620626
59 + 8620567 = 8620626
73 + 8620553 = 8620626
83 + 8620543 = 8620626
97 + 8620529 = 8620626
127 + 8620499 = 8620626

Showing the first eight; more decompositions exist.
