Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109928, here are decompositions:

31 + 109897 = 109928
37 + 109891 = 109928
79 + 109849 = 109928
97 + 109831 = 109928
109 + 109819 = 109928
139 + 109789 = 109928
211 + 109717 = 109928
307 + 109621 = 109928

Showing the first eight; more decompositions exist.
