Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71992, here are decompositions:

5 + 71987 = 71992
29 + 71963 = 71992
59 + 71933 = 71992
83 + 71909 = 71992
113 + 71879 = 71992
131 + 71861 = 71992
149 + 71843 = 71992
251 + 71741 = 71992

Showing the first eight; more decompositions exist.
