Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620904, here are decompositions:

7 + 8620897 = 8620904
31 + 8620873 = 8620904
43 + 8620861 = 8620904
157 + 8620747 = 8620904
181 + 8620723 = 8620904
241 + 8620663 = 8620904
283 + 8620621 = 8620904
337 + 8620567 = 8620904

Showing the first eight; more decompositions exist.
