Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71500, here are decompositions:

17 + 71483 = 71500
29 + 71471 = 71500
47 + 71453 = 71500
71 + 71429 = 71500
89 + 71411 = 71500
101 + 71399 = 71500
113 + 71387 = 71500
137 + 71363 = 71500

Showing the first eight; more decompositions exist.
