Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620850, here are decompositions:

3 + 8620847 = 8620850
103 + 8620747 = 8620850
127 + 8620723 = 8620850
163 + 8620687 = 8620850
211 + 8620639 = 8620850
229 + 8620621 = 8620850
283 + 8620567 = 8620850
307 + 8620543 = 8620850

Showing the first eight; more decompositions exist.
