Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31932, here are decompositions:

41 + 31891 = 31932
59 + 31873 = 31932
73 + 31859 = 31932
83 + 31849 = 31932
139 + 31793 = 31932
163 + 31769 = 31932
181 + 31751 = 31932
191 + 31741 = 31932

Showing the first eight; more decompositions exist.
