Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71890, here are decompositions:

3 + 71887 = 71890
11 + 71879 = 71890
23 + 71867 = 71890
29 + 71861 = 71890
41 + 71849 = 71890
47 + 71843 = 71890
53 + 71837 = 71890
83 + 71807 = 71890

Showing the first eight; more decompositions exist.
