Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71424, here are decompositions:

5 + 71419 = 71424
11 + 71413 = 71424
13 + 71411 = 71424
37 + 71387 = 71424
61 + 71363 = 71424
71 + 71353 = 71424
83 + 71341 = 71424
97 + 71327 = 71424

Showing the first eight; more decompositions exist.
