Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71866, here are decompositions:

5 + 71861 = 71866
17 + 71849 = 71866
23 + 71843 = 71866
29 + 71837 = 71866
59 + 71807 = 71866
89 + 71777 = 71866
167 + 71699 = 71866
173 + 71693 = 71866

Showing the first eight; more decompositions exist.
