Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9850, here are decompositions:

11 + 9839 = 9850
17 + 9833 = 9850
47 + 9803 = 9850
59 + 9791 = 9850
83 + 9767 = 9850
101 + 9749 = 9850
107 + 9743 = 9850
131 + 9719 = 9850

Showing the first eight; more decompositions exist.
