Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71418, here are decompositions:

5 + 71413 = 71418
7 + 71411 = 71418
19 + 71399 = 71418
29 + 71389 = 71418
31 + 71387 = 71418
59 + 71359 = 71418
71 + 71347 = 71418
79 + 71339 = 71418

Showing the first eight; more decompositions exist.
