Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71832, here are decompositions:

11 + 71821 = 71832
23 + 71809 = 71832
43 + 71789 = 71832
71 + 71761 = 71832
113 + 71719 = 71832
139 + 71693 = 71832
199 + 71633 = 71832
239 + 71593 = 71832

Showing the first eight; more decompositions exist.
