Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71908, here are decompositions:

29 + 71879 = 71908
41 + 71867 = 71908
47 + 71861 = 71908
59 + 71849 = 71908
71 + 71837 = 71908
101 + 71807 = 71908
131 + 71777 = 71908
167 + 71741 = 71908

Showing the first eight; more decompositions exist.
