Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71722, here are decompositions:

3 + 71719 = 71722
11 + 71711 = 71722
23 + 71699 = 71722
29 + 71693 = 71722
59 + 71663 = 71722
89 + 71633 = 71722
173 + 71549 = 71722
239 + 71483 = 71722

Showing the first eight; more decompositions exist.
