Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71930, here are decompositions:

13 + 71917 = 71930
31 + 71899 = 71930
43 + 71887 = 71930
109 + 71821 = 71930
211 + 71719 = 71930
223 + 71707 = 71930
283 + 71647 = 71930
337 + 71593 = 71930

Showing the first eight; more decompositions exist.
