Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620636, here are decompositions:

5 + 8620631 = 8620636
47 + 8620589 = 8620636
83 + 8620553 = 8620636
107 + 8620529 = 8620636
137 + 8620499 = 8620636
347 + 8620289 = 8620636
359 + 8620277 = 8620636
419 + 8620217 = 8620636

Showing the first eight; more decompositions exist.
