Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31956, here are decompositions:

73 + 31883 = 31956
83 + 31873 = 31956
97 + 31859 = 31956
107 + 31849 = 31956
109 + 31847 = 31956
139 + 31817 = 31956
157 + 31799 = 31956
163 + 31793 = 31956

Showing the first eight; more decompositions exist.
