Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71912, here are decompositions:

3 + 71909 = 71912
13 + 71899 = 71912
31 + 71881 = 71912
103 + 71809 = 71912
151 + 71761 = 71912
193 + 71719 = 71912
199 + 71713 = 71912
241 + 71671 = 71912

Showing the first eight; more decompositions exist.
