Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71406, here are decompositions:

7 + 71399 = 71406
17 + 71389 = 71406
19 + 71387 = 71406
43 + 71363 = 71406
47 + 71359 = 71406
53 + 71353 = 71406
59 + 71347 = 71406
67 + 71339 = 71406

Showing the first eight; more decompositions exist.
