Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71856, here are decompositions:

7 + 71849 = 71856
13 + 71843 = 71856
19 + 71837 = 71856
47 + 71809 = 71856
67 + 71789 = 71856
79 + 71777 = 71856
137 + 71719 = 71856
149 + 71707 = 71856

Showing the first eight; more decompositions exist.
