Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71256, here are decompositions:

7 + 71249 = 71256
19 + 71237 = 71256
23 + 71233 = 71256
47 + 71209 = 71256
89 + 71167 = 71256
103 + 71153 = 71256
109 + 71147 = 71256
113 + 71143 = 71256

Showing the first eight; more decompositions exist.
