Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31992, here are decompositions:

11 + 31981 = 31992
19 + 31973 = 31992
29 + 31963 = 31992
101 + 31891 = 31992
109 + 31883 = 31992
193 + 31799 = 31992
199 + 31793 = 31992
223 + 31769 = 31992

Showing the first eight; more decompositions exist.
