Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9806, here are decompositions:

3 + 9803 = 9806
19 + 9787 = 9806
37 + 9769 = 9806
67 + 9739 = 9806
73 + 9733 = 9806
109 + 9697 = 9806
127 + 9679 = 9806
157 + 9649 = 9806

Showing the first eight; more decompositions exist.
