Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71662, here are decompositions:

29 + 71633 = 71662
113 + 71549 = 71662
179 + 71483 = 71662
191 + 71471 = 71662
233 + 71429 = 71662
251 + 71411 = 71662
263 + 71399 = 71662
401 + 71261 = 71662

Showing the first eight; more decompositions exist.
