Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618850, here are decompositions:

17 + 8618833 = 8618850
41 + 8618809 = 8618850
61 + 8618789 = 8618850
67 + 8618783 = 8618850
101 + 8618749 = 8618850
103 + 8618747 = 8618850
113 + 8618737 = 8618850
151 + 8618699 = 8618850

Showing the first eight; more decompositions exist.
