Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71628, here are decompositions:

31 + 71597 = 71628
59 + 71569 = 71628
79 + 71549 = 71628
101 + 71527 = 71628
149 + 71479 = 71628
157 + 71471 = 71628
191 + 71437 = 71628
199 + 71429 = 71628

Showing the first eight; more decompositions exist.
